 Importing Fonts
 ===============
 
-.. image:: images/import_font.png
+Crown can import fonts from popular font file formats. Importing a font produces
+a ``.font`` resource (a map of glyphs), an accompanying ``.texture`` resource
+(an atlas containing all the glyphs) and a ``.material`` resource suitable for
+drawing text.
+
+.. figure:: images/import_font.png
+   :align: center
+
+   The Import Font dialog.
+
+Dialog overview
+===============
+
+On the left, the importer shows a preview of the final texture atlas. On the
+right you can set various parameters that control which characters are included
+in the atlas and their size. This size does not have to match the size used when
+drawing text, but it is good practice to keep them similar to avoid scaling
+artifacts.
+
+Renaming the font
+=================
+
+Font files are often named with variants and other details embedded in the
+filename. If you prefer a simpler name, you can rename the font before
+importing by entering it in the ``Name`` field.
+
+Atlas generation
+================
+
+The atlas dimensions are shown in ``Atlas size``. They are determined
+automatically from the font ``Size`` and the selected ``Charset``. Enter the
+desired font size and press ``Enter``; Crown will regenerate the atlas and
+update the preview. Glyphs are packed as tightly as possible to keep the
+atlas small and avoid runtime performance issues.
+
+Custom charset
+==============
+
+By default Crown provides several common character sets in the ``Charset``
+dropdown. For a custom range, use ``Range min`` and ``Range max`` to set the
+first and last Unicode code point to include in the font.

+The quickest way to import assets into a Crown project is to drag-and-drop
+files from your file manager into the Project Browser. Crown will detect the
+resource types automatically and open an appropriate importer dialog so you
+can fine-tune import options.
+
+Import via Project Browser
+--------------------------
+
+.. figure:: images/project_browser_right_click_import.png

+
+   Importing resources via the Project Browser context menu.

+
+.. figure:: images/import_dialog.svg
+   :align: center
+
+   The Import dialog for picking files and choosing the resource type.
+
+This method is useful when you want more control: the Import dialog lets you
+choose how Crown should process the selected files. That matters because the
+same file extension can sometimes map to different resource types
+(for example, ``.png`` files can be imported as textures or as sprites). Use

+
+Importing Scenes
+================
+
+Crown can import most useful elements from 3D scenes saved in FBX format. When
+you import an FBX file, Crown opens a dialog where you can select import
+options and choose which parts of the scene to bring into your project:
+
+.. figure:: images/import_fbx.png
+   :align: center
+
+   The FBX import dialog.
+
+FBX import dialog
+-----------------
+
+The FBX import dialog is divided into two main sections:
+
+* Units: import geometry, lights, cameras, materials and any associated
+  textures.
+* Animation: import skeleton and animation clips. If your scene contains no
+  animations, you can ignore this section.
+
+One FBX per clip
+----------------
+
+A common workflow for animated 3D models is to export the geometry and
+skeleton together in one FBX file, and export each animation clip as a
+separate FBX file. Crown supports and recommends this approach because it
+simplifies asset management and make faster iterations possible.
+
+To import models organized in this way, always follow these 2 steps:
+
+1) Importing geometry and skeleton
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Start by importing the FBX that contains the geometry and skeleton. In the
+Project Browser create or select the target folder, make sure ``Import
+Animations`` is unchecked, then click ``Import`` to begin:
+
+.. figure:: images/import_fbx_unchecked_animations.svg
+   :align: center
+
+   Disabling animation import when importing geometry and skeleton.
+
+When the import completes, the unit (geometry), the skeleton, and any other
+objects you selected in the Unit section will appear as separate items in the
+Project Browser:
+
+.. figure:: images/project_browser_import_clips_unit_and_skeleton.svg
+   :align: center
+
+   Imported unit, skeleton, and related resources in the Project Browser.
+
+2) Importing animation clips
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After importing geometry and skeleton, import the FBX files that contain the
+individual animation clips. Right-click the same folder, choose
+``Import...``, and select the FBX files with the clips. In the importer
+dialog:
+
+* Uncheck the entire **Unit** section to avoid importing any undesired resource.
+* Uncheck ``New Skeleton`` to indicate that the skeleton already exists.
+* Set ``Target Skeleton`` to the skeleton you imported in the previous step.
+
+.. figure:: images/import_fbx_select_skeleton.svg
+   :align: center
+
+   Selecting the target skeleton when importing animation clips.
+
+When the importer finishes, it creates an ``animations`` folder and places the
+imported clips inside it, with correct references to the existing skeleton and
+geometry:

 Importing Sprites
 =================
 
-.. image:: images/import_sprite.png
+Crown includes a dedicated spritesheet importer with slicing capabilities that
+let you quickly create Units from images containing sprites arranged in rows
+and columns. When importing a new spritesheet, it is recommended to create a
+dedicated target folder first. The importer generates multiple output files
+(sprites, units, materials etc.), so keeping them together makes the project
+easier to manage.
+
+.. figure:: images/import_sprite.png
+   :align: center
+
+   The Sprite Importer window.
+
+Sprite Importer overview
+------------------------
+
+The importer window is split into a preview area, a slicing view, and a panel
+with import options:
+
+The top-left corner contains two tabs:
+
+* ``Preview``: shows how the sprite will look after import.
+* ``Slices``: displays a grid view to help you choose slicing parameters.
+
+The panel on the right holds slicing parameters and options for rendering and
+phyisics. Most of these settings can be changed after import, so you do not
+need to get everything perfect on the first pass.
+
+Slicing the spritesheet
+-----------------------
+
+Slicing defines how the image is split into individual sprite cells.
+
+* ``Cells``: set the number of columns (X) and rows (Y). This creates an X by
+  Y grid of equally sized cells.
+* ``Auto Size``: when checked, Crown computes the cell size automatically.
+  Uncheck it to enter cell width and height manually.
+* ``Offset``: shift the entire grid horizontally and vertically when cells are
+  not aligned to the image origin.
+* ``Spacing``: add horizontal and vertical spacing between cells when the
+  spritesheet contains padding.
+
+Adjust the grid in the ``Slices`` tab and verify results in the ``Preview``
+tab before importing.
+
+Pivot (sprite origin)
+---------------------
+
+Choose the sprite origin with the ``Pivot`` combobox. The preview area shows
+the pivot position so you can pick the point that makes placement and
+rotation easier.
+
+.. figure:: images/sprite_pivot.svg
+   :align: center
+
+   The sprite pivot in the preview area.
+
+Collision and physics
+---------------------
+
+By default Crown generates a collider and physics parameters every time you
+import a sprite. Disable collision generation by unchecking the ``Collision``
+option if you only need a visual unit.
+
+Crown supports three collider shapes for sprites:
+
+* ``Square``
+* ``Circle``
+* ``Capsule``
+
+Use the ``Shape Type`` buttons to switch between them. By default the collider
+is fitted to the cell rectangle determined during slicing. To customize the
+collider:
+
+* Uncheck ``Mirror Cell`` to stop the collider from mirroring the cell bounds.
+* Edit ``Shape Data`` to input collider sizes manually.

+
+===============
+Editor overview
+===============
+
+After opening a :ref:`project` Crown immediately starts compiling the
+resources it contains. Once the process is complete, the Level Editor is
+launched and should look similar to the image below:
+
+.. figure:: images/editor_overview.svg
+   :align: center
+
+   The Level Editor interface in its default configuration.
+
+The Level Editor is split into several panels:
+
+====== ======================= =============
+Number Name                    What it shows
+====== ======================= =============
+1      :ref:`Project Browser`  The current project's contents.
+2      :ref:`Console`          Messages from the Level Editor, the Game and other Runtimes.
+3      :ref:`Inspector`        The properties of the currently selected object.
+4      :ref:`Level Tree`       A hierarchical view of all the objects in the Level.
+5      :ref:`Level Viewport`   The Level being edited.
+6      Menubar                 Common commands for editing / debugging / opening editors etc.
+7      Toolbar                 Tools and common options for editing.
+8      Statusbar               Contextual info and small self-contained messages.
+9      Titlebar                Start/Stop Level button, current level name and edit status.
+====== ======================= =============
+
+Layout customization
+====================
+
+Most panels are optional and can be toggled from the ``View`` menu in the
+Menubar.
+
+The Console can be shown or hidden quickly with the ``Ctrl+``` shortcut. Use
+the same shortcut to jump to the Command Bar in the Console.
+
+Running the game
+================
+
+Press ``F5`` to play the currently edited level. Crown saves a copy of the
+level you are editing and launches it in a separate window. When the level is
+running, the Console automatically connects to the game's runtime and
+switches to communicate with it.
+
+To stop the playtest, close the game window or press the Stop Level button on
+the Titlebar. If the runtime takes too long to stop, it will be forcibly
+terminated. At exit the Console will switch back to communicating with the
+editor's runtime.
+
+To run the full game, choose ``Debug -> Run Game`` from the Menubar. In this
+mode Crown launches the game as it would run for an end user.

+Level Tree
+==========
+
+The Level Tree shows a hierarchical view of the objects in the current Level.
+Use it to inspect structure, organize items, and perform common actions such
+as duplicating, renaming, and saving Units as prefabs.
+
+.. figure:: images/level_tree.png

+
+   The Level Tree showing some Units in a Level and an empty Sounds folder.
+
+Saving Unit prefabs
+===================
+
+Right-click any Unit in the tree and choose ``Save as Prefab...``. In the file
+dialog that opens, pick a unique name for the prefab and click ``Save``. The
+command creates a reusable prefab resource you can place in other Levels.
+
+Renaming objects
+================
+
+Objects receive an automatic name when created. To give an object a clearer
+name, right-click it in the Level Tree and choose ``Rename...`` from the
+context menu. Descriptive names are useful when you need to refer to objects
+by name from :ref:`gameplay code <getting_unit_handles>`.
+
+Searching and sorting
+=====================
+
+Use the Search Bar at the top of the Level Tree to find objects by name. Begin
+typing and matching objects appear instantly; press ``Esc`` to exit search
+mode. The button to the right of the Search Bar let you choose the sorting
+criteria to change how items are ordered in the tree.

+==============
+Level Viewport
+==============
+
+This section describes how to navigate the Level Viewport so you can inspect,
+edit, and compose scenes comfortably. The viewport supports both quick,
+mouse-only navigation for casual inspection and more precise, keyboard-plus-
+mouse controls for editing and layout work.
+
+Basic mouse navigation
+======================
+
+If you only need a quick look around, the mouse provides simple and immediate
+controls. Rolling the mouse wheel zooms the camera in and out. Clicking and
+dragging the ``Middle Mouse Button`` orbits the view around the current
+interest point. The orbit center typically coincides with the last framed
+selection, so framing an object first (see the :ref:`Framing objects`
+section) gives you a predictable pivot for orbiting.
+
+Keyboard + mouse navigation
+===========================
+
+For more controlled camera adjustments, combine keyboard modifiers with mouse
+actions.
+
+* Hold ``Left Alt`` while dragging with the ``Left Mouse Button`` to rotate
+  around the interest point;
+* Hold ``Left Alt`` and drag with the ``Middle Mouse Button`` to pan the view
+  horizontally and vertically;
+* Hold ``Left Alt`` and drag with the ``Right Mouse Button`` to zoom in and
+  out.
+
+Flythrough navigation
+=====================
+
+When you need to traverse the level at speed, use flythrough mode. Hold the
+``Right Mouse Button`` to control the camera orientation with the mouse, then
+use the keyboard to move the camera as if you were playing a first-person
+game:
+
+* ``W`` / ``S`` to move forward and backward;
+* ``A`` / ``D`` to strafe left and right;
+* ``Q`` / ``E`` to move the camera up and down.
+
+Flythrough mode is handy for scanning large environments, testing sightlines,
+or checking level flow at player height.
+
+Selecting objects
+=================
+
+Selecting objects is the primary way to focus edits and transformations on
+specific objects in the scene. Left-click an object to select it; a dim
+orange outline will be drawn around selected objects in the viewport:
+
+.. figure:: images/selected_cube.png
+   :align: center
+
+   A selected cube highlighted in the Level Viewport.
+
+If a selected object is occluded by unselected ones, Crown still highlights it
+with a slightly dimmed orange outline so you can keep working with it even
+when it is not fully visible:
+
+.. figure:: images/selected_sphere_occluded.png
+   :align: center
+
+   A selected sphere with dimmed highlighting where occluded.
+
+To clear the current selection, just left-click an empty area or press
+``Shift + Ctrl + A``.
+
+Multiple selection
+------------------
+
+Hold ``Left Shift`` while left-clicking to add unselected objects to the
+current selection. Conversely, left-click an already selected object to
+remove it from the selection.
+
+To select multiple objects by area, left-click and drag to draw a selection
+rectangle; any object that intersects that rectangle will be selected.
+
+.. figure:: images/box_selection.png
+   :align: center
+
+   Box selection in the Level Viewport.
+
+Framing objects
+===============
+
+Framing centers and zooms the camera on selected objects so you can work on
+them with a consistent viewpoint.
+
+Select one or more objects and press ``F`` to frame the current selection; the
+camera will pan and zoom so the selected objects fill the viewport
+comfortably. Press ``A`` to frame the entire scene.
+
+Framing is especially useful before orbiting or when you want to set a stable
+interest point for subsequent camera manipulations.
+
+Placing objects
+===============
+
+Place content into the scene by entering place mode or by dragging units from
+the Project Browser.
+
+Press ``Q`` to enter place mode; the cursor then becomes a placement tool and
+a chosen unit can be spawned with a mouse click. If no unit is selected for
+spawning, clicks have no effect. At any time, press ``Esc`` to exit placing
+mode: Crown will enter the tool that was active before entering place mode.
+
+Dragging a Unit directly from the Project Browser into the Level Viewport
+automatically selects the Spawn tool and sets the dragged unit as the current
+spawn candidate.
+
+Click the ``Left Mouse Button`` to place the unit. By default Crown raycasts
+from the camera origin through the mouse cursor to determine the Z height
+where the unit should be positioned. If you click and hold the ``Left Mouse
+Button``, then move the mouse, Crown will place the unit at any XY location
+on the horizontal plane defined by the height where you first clicked. This
+lets you position objects precisely along a fixed elevation.
+
+Moving, rotating, and scaling objects
+=====================================
+
+Transform objects with the standard ``W``, ``E``, and ``R`` keys to enter
+Move, Rotate, and Scale modes respectively.
+
+When one or more objects are selected, Crown displays a transform gizmo at the
+origin of the selection. The gizmo provides axis handles, planar handles and
+a camera-aligned handle. Interact with the gizmo using left-click and drag.
+
+.. figure:: images/move_rotate_scale.png
+   :align: center
+
+   Move, rotate, and scale gizmos in the Level Viewport.
+
+Move gizmo
+----------
+
+* Left-click and drag an axis handle to move the object along that axis.
+* Drag the small red, green, or blue rectangles to move the object constrained
+  to the XY, YZ, or ZX plane respectively.
+* Drag the small gray circle at the gizmo origin to move the object on the
+  plane parallel to the camera view.
+
+Rotate gizmo
+------------
+
+* Drag any red, green, or blue arc to rotate the object around the X, Y, or Z
+  axis.
+* Drag the large gray circle to rotate the object around the axis that is
+  perpendicular to the camera view plane.
+
+Scale gizmo
+-----------
+
+* Drag an axis handle to scale the object along that axis.
+* Drag the colored rectangles (for example red-green to scale on the XY plane)
+  to scale across the respective plane.
+* Drag the large gray circle to scale uniformly on all axes at once.
+
+Local and World axis
+--------------------
+
+Normally, gizmo axes are aligned to the local coordinate system of the
+selected object. That makes transforms intuitive when you want to move,
+rotate, or scale an object relative to its own orientation. However, when an
+object is rotated inconveniently, local axes can make it difficult to perform
+edits that must align to the scene or the world origin.
+
+Switching to the ``World Axis`` mode forces all gizmos to align to the world
+coordinate system regardless of the selected object's local transformations.
+
+Toggle axis mode using the Local/World Axis control in the toolbar:
+
+.. figure:: images/local_world_axis.svg
+   :align: center
+
+   Toggling between local and world axis modes.
+
+Snapping
+========
+
+By default Crown lets you position and rotate objects freely. When you require
+precision, enable grid and angle snapping to constrain transforms to fixed
+increments. Toggle snapping by clicking the ``Snap To Grid`` button on the
+toolbar:
+
+.. figure:: images/toolbar_snap_to_grid.svg
+   :align: center
+
+   The Snap To Grid control in the toolbar.
+
+With snapping enabled, movement and rotation will snap to the configured grid
+size and snap angle. Hold ``Left Ctrl`` while performing a transform to
+temporarily disable snapping and make a single free adjustment.
+
+Change the grid cell size or the snap angle with ``Ctrl+G`` and ``Ctrl+H``
+respectively. These shortcuts open dialogs where you can type exact numeric
+values for the grid spacing and angle increment:
+
+.. figure:: images/grid_size_dialog.png
+   :align: center
+
+   Configuring grid size and snap angle.
+
+Relative and Absolute snapping
+------------------------------
+
+Crown offers two snapping coordinate modes. In Relative Snapping mode the
+snapping grid origin is aligned to the origin of the object being
+transformed; this makes the grid move together with the object and is
+convenient for local adjustments.
+
+In Absolute Snapping mode the snapping grid is fixed at the world origin,
+which is useful for aligning multiple objects to a common global grid.
+
+Switch between the two modes using the ``Relative Snap`` and ``Absolute Snap``
+toolbar buttons.

+
+.. figure:: images/project_browser.png
+   :align: center
+
+   The Project Browser showing folders and resources.
+
+Overview
+========
+
+By default the Project Browser is split into two panes. The top pane shows a
+tree view of the project folders. The bottom pane, called the Folder View,
+displays the contents of the currently selected folder.
+
+If you prefer a single unified view that shows files and folders together,
+click the small tree icon at the top-right to toggle the layout mode:
+
+.. figure:: images/project_browser_tree_view.svg
+   :align: center
+
+   The layout toggle in the Project Browser.
+
+Folder View
+===========
+
+The Folder View presents the resources inside the selected folder. You can
+switch between a icon view and a compact list view using the button at the
+top-right of the Folder View:
+
+.. figure:: images/project_browser_icon_list_view.svg
+   :align: center
+
+   Switching between icon and list views in the Folder View.
+
+Resources such as units, materials, textures and other graphical content use

+   Thumbnail previews for graphical resources in the Project Browser.
+
+Thumbnails generated in Crown are saved in a dedicated OS location so they can
+be used by other programs such as the file manager.
+
+Files visibility
+================
+
+To keep the Project Browser uncluttered, the UI normally hides auxiliary files
+and shows resources as a single item with trimmed extension. For example, a
+texture resource on disk consists of the original image file plus a generated
+``.texture`` resource file; the browser shows them as one combined
+``.texture`` item. Similar grouping applies to other resource types.
+
+When you need to inspect the actual files on disk use the button immediately
+to the right of the Search Bar to toggle visibility options:
+
+.. figure:: images/project_browser_sorting_filtering.svg
+   :align: center
+
+   The visibility and sorting controls in the Project Browser.
+
+With the same popup you can also control how the items should be sorted.
+
+Searching
+=========
+
+The Project Browser offers fast project-wise searching based on keywords.
+Start typing in the Search Bar and matching results appear as you type. Press
+``Escape`` to exit search mode. The Search Bar position may move depending on
+the current view mode (icon view or tree view), but the search behavior
+remains the same.
+
+Search context
+--------------
+
+By default the search covers the project itself (i.e. the main source dir). If
+your project includes mapped source directories, those are excluded from
+search results unless you enable them explicitly by checking ``Show mapped
+dirs`` in the :ref:`visibility controls <Files Visibility>`.

+
+.. figure:: images/texture_settings_dialog.png
+   :align: center
+
+   The Texture Settings dialog.
+
+Overview
+--------
+
+On the left, the ``Target Platform`` list shows the platforms you can
+configure. Select one or more platforms to edit their settings
+simultaneously. Use ``Left Ctrl`` to select or deselect multiple entries.
+
+After selecting platforms, the settings on the right update to reflect the

+.. figure:: images/texture_settings_inconsistent_format.svg
+   :align: center
+
+   Inconsistent format values indicated by a dash symbol.
+
+Output
+------
+
+Output settings control how Crown processes the source image into GPU-ready
+assets. These settings are applied per platform so you can accommodate each
+platform's performance and form-factor constraints.
+
+Format
+~~~~~~
+
+Choose the output format appropriate for the texture type and platform:
+
+* ``BC1``: RGB color with 1-bit alpha; good for opaque color maps.
+* ``BC2``: RGB color with 4-bits alpha.
+* ``BC3``: RGB color with full alpha.
+* ``BC4``: Single-channel (grayscale); useful for heightmaps, font atlases etc.
+* ``BC5``: Two-channel BC4 useful for tangent-space normal maps.
+* ``PTC14``: RGB compressed format.
+* ``RGB8``: Uncompressed RGB (8-bits per channel).
+* ``RGBA8``: Uncompressed RGBA (8-bits per channel).
+
+For a technical reference on BCn formats, see `Understanding BCn Texture Compression Formats <https://web.archive.org/web/20260120185114/https://www.reedbeta.com/blog/understanding-bcn-texture-compression-formats/>`_.
+
+Mip-mapping
+~~~~~~~~~~~
+
+Control mipmap generation with these options:
+
+* ``Generate Mips``: enable or disable automatic mipmap generation.
+* ``Skip Smallest Mips``: skip generation of the N smallest mip levels to save space.
+
+Other flags
+~~~~~~~~~~~
+
+* ``Normal Map``: mark the texture as a normal map. This implies linear color
+  processing.
+* ``Linear``: treat the source as linear data. By default textures are
+  interpreted as sRGB and are converted to linear space during processing;
+  enable ``Linear`` for data textures such as normal maps, LUTs etc.
+* ``Premultiply Alpha`` - premultiply RGB by alpha before encoding. See
+  `here
+  <https://web.archive.org/web/20260110150156/https://shawnhargreaves.com/blog/premultiplied-alpha.html>`_

+=====================
+Global Physics Config
+=====================
+
+The ``global.physics_config`` resource defines physics materials, collision
+filters, and actor classes used by Crown's physics simulation. The file is
+stored in SJSON format and must be edited manually.
+
+Example
+=======
+
+.. code-block::
+
+    materials = {
+        default = { friction = 0.8 restitution = 0.81 }
+    }
+

+        static = { dynamic = false }
+        dynamic = { dynamic = true }
+        keyframed = { dynamic = true kinematic = true disable_gravity = true }
+        trigger = { trigger = true }
+    }
+
+.. _physics_materials:
+
+Materials
+=========
+
+Physics materials define surface response parameters for :ref:`actors
+<Actors>`. Create a new material by adding an entry to the ``materials``
+object:
+
+.. code-block::
+
+    materials = {
+        default = ...
+        slippery = { friction = 0.1 }
+    }
+
+Common material properties:
+
+* ``friction``: general contact friction; larger values increase resistance to
+  sliding.
+* ``rolling_friction``: torsional friction orthogonal to the contact normal;
+  helps stop spheres rolling forever.
+* ``spinning_friction``: torsional friction around the contact normal; useful
+  for grasping.
+* ``restitution``: coefficient of restitution; 1 = perfectly elastic
+  collision, < 1 = inelastic.
+
+Collision filters
+=================
+
+Collision filters control which :ref:`actors <Actors>` interact with which. Define a
+filter by adding an entry to the ``collision_filters`` object:
+
+.. code-block::
+
+    collision_filters = {
+        ...
+        wall = {}
+        player = { collides_with = [ "wall" ] }
+    }
+
+The filter name (for example ``player``) can then be assigned to actors. Use
+``collides_with`` to list specific filters this filter should collide with,
+or ``collides_with_all_except`` to collide with everything except the
+specified filters.
+
+Collision rule
+--------------
+
+Two actors A and B generate collisions if either of the following is true:
+
+* A's filter has B in its ``collides_with`` set, or
+* B's filter has A in its ``collides_with`` set.
+
+Actor classes
+=============
+
+Actor classes are used to specify simulation properties to apply
+to :ref:`Actors`. Define classes inside the ``actors`` object:
+
+.. code-block::
+
+    actors = {
+        static = { dynamic = false }
+        dynamic = { dynamic = true }
+        keyframed = { dynamic = true kinematic = true disable_gravity = true }
+        trigger = { trigger = true }
+    }
+
+Common actor class properties:
+
+* ``linear_damping``: resistance applied to linear motion; useful to slow down
+  objects unaffected by friction.
+* ``angular_damping``: resistance applied to angular motion.
+* ``dynamic``: when true, the actor is simulated each frame by the physics
+  engine. If false, the actor cannot move but just collide.
+* ``kinematic``: when true, the actor is driven externally (animation or code)
+  rather than by physics. Kinematic objects push dynamic objects away but are
+  unaffected by them.
+* ``disable_gravity``: disables gravity for the actor.
+* ``trigger``: actor does not produce collision responses but still generates
+  overlap events.

+Rigid Bodies
+============

+physical behaviour.
+
+.. figure:: images/actor_component.png
+   :align: center
+
+   The Actor Component shown in the Inspector.
+
+Colliders
+=========
+
+Colliders define an Actor's physical shape. The shape can be derived from mesh
+geometry or specified manually. When using a mesh as the source you can
+choose between fast analytic shapes (``sphere``, ``capsule`` or ``box``) or
+more accurate representations such as ``convex_hull`` or ``mesh``.
+
+.. figure:: images/collider_component.png
+   :align: center
+
+   The Collider Component shown in the Inspector.
+
+Analytic shapes are much cheaper to simulate and are recommended whenever they
+provide acceptable results; use convex or full mesh shapes only when you need
+precise collision geometry.
+
+Only analytic shapes can be specified manually.
+
+Actors
+======
+
+Actors provide physical behaviour to the Unit they are attached to. An Actor
+defines the physical object's :ref:`class <Actor classes>`,
+its :ref:`material <physics_materials>`, :ref:`collision filter <Collision
+filter>`, mass, and other simulation properties.
+
+Actor Class
+-----------
+
+A project defines a set of global actor classes. The default classes are
+described below:
+
+* ``static``: immovable actors, they just collide.
+* ``dynamic``: fully simulated actors affected by forces and collisions.
+* ``keyframed``: actors driven by animation or code; they push away dynamic
+  actors but are not influenced by them.
+* ``trigger``: non-blocking actors used to detect overlap events.
+
+You can define additional classes and tune class behavior in the :ref:`Global
+Physics Config`.
+
+Collision Filter
+----------------
+
+Collision filters control which actors interact with which. The ``default``
+filter applied to new actors allows interaction with other actors using the
+same ``default`` filter. A ``no_collision`` filter is available to make
+actors ignore collisions entirely.
+
+Custom, arbitrarily complex filters can be added and configured via
+the :ref:`Global Physics Config`.
+
+Material
+--------
+
+Materials specify the physical properties of actors. Create new materials in
+the :ref:`Global Physics Config`.
+
+Movers
+======
+
+The Mover Component is a specialized kinematic actor that implements classic
+collide-and-slide behavior and is better suited for character controllers and
+NPCs that require deterministic movement under direct control of the player
+or scripts.

+Lighting
+========
+
+Crown provides three light types: directional, omni, and spot. Lights are
+regular :ref:`Units` with a Light Component attached; the component's
+``Type`` property selects the light type. Add a light to the level using
+``Spawn`` -> ``Light`` in the :ref:`Menubar <Editor overview>`.
+
+Directional light
+=================
+
+A directional light illuminates objects from a uniform direction; The
+brightest directional light in a Level (the one with the highest
+``Intensity``) is considered the sun. The sun typically renders shadows for
+the entire level using Cascaded Shadow Maps. Crown adds a default sun unit to
+new levels created from the :ref:`Level Editor <level_editor>`.
+
+.. figure:: images/lights_directional.png
+   :align: center
+
+   A directional light illuminating objects in the Level Viewport.
+
+Local lights
+============
+
+Local lights affect only nearby objects. They expose a maximum range property
+to limit their influence. Keep ranges reasonably small to reduce performance
+cost and to avoid shadowing artifacts; very large ranges can make shadows and
+lighting harder to tune.
+
+Omni light
+----------
+
+Omni lights emit in all directions and are suitable for simulating point light
+sources such as light bulbs, fireplaces and so on.
+
+.. figure:: images/lights_omni.png
+   :align: center
+
+   An omni light illuminating objects in the Level Viewport.
+
+Spot light
+----------
+
+Spot lights emit light inside a cone. Use the Light Component's ``Spot Angle``
+and ``Range`` to shape the cone. Spot lights are appropriate for torches,
+street lights and similar sources.
+
+.. figure:: images/lights_spot.png
+   :align: center
+
+   A spot light illuminating objects in the Level Viewport.
+
+Shadows
+=======
+
+Crown uses different shadow mapping approaches depending on the light type.
+Directional light shadows are rendered with Cascaded Shadow Maps (4 splits).
+Local lights combine tetrahedron mapping and regular shadow maps inside a
+single shadow atlas. Use the :ref:`Render Config` to tune shadow-map
+resolution and related parameters.
+
+Rendering convincing shadows require careful tuning. Two common shadow mapping
+artifacts are shadow acne and peter-panning. Use the Light Component's
+``Shadow Bias`` property to reduce these issues.
+
+The ``Shadow Bias`` offsets depth comparisons to compensate for shadow map
+precision limits. Lower bias values reduce peter-panning but can expose
+shadow acne; higher bias values reduce acne but can cause noticeable
+separation between casting objects and their shadows (peter-panning). Adjust
+bias incrementally to find the best compromise for your Level.
+
+.. figure:: images/shadow_artifacts.png
+   :align: center
+
+   Left: shadow acne (low bias). Right: peter-panning (high bias).
+
+Skydome
+=======
+
+Crown automatically adds an implicit skydome Unit to every new Level created
+with the :ref:`Level Editor <level_editor>`. It is rendered on the current
+camera's far plane and is always centered to it, so it appears infinitely
+distant and does not shift as the camera moves. Its texture and intensity are
+configured via the :ref:`Shading Environment <Global Lighting>`.

+Materials
+=========
+
+Materials in Crown are resources with the ``.material`` extension. They define
+the shading (i.e. the visual appearance) of objects in the scene.
+
+.. figure:: images/materials.png
+   :align: center
+
+   Some materials displayed in the Project Browser.
+
+At the technical level, a material binds a shader together with its options
+and parameters (uniforms and samplers). For example, the built-in
+``core/units/primitive`` material uses the shader named ``mesh`` and assigns
+values appropriate to primitive objects to all uniforms that shader exposes.
+
+Creating Materials
+==================
+
+Materials are normally created indirectly by the :ref:`importers
+<importing_resources>` when you bring in external resources.
+
+For instance:
+
+* Importing a 3D scene automatically generates the required ``.material``
+  resources
+* Importing sprites also produces associated material resources
+
+You can also create standalone materials directly in the :ref:`Level Editor
+<level_editor>`:
+
+1. Open the :ref:`Project Browser`
+2. Right-click inside the target folder
+3. Choose ``New Material...``
+4. Give it a unique name and confirm
+
+Assigning Materials to Units
+============================
+
+Materials are assigned to units through their rendering components. The ``Mesh
+Renderer`` component for example exposes a ``Material`` property.
+
+.. figure:: images/mesh_renderer_material.svg
+   :align: center
+
+   The Material selector in the Mesh Renderer component.
+
+Click the folder icon next to the material's name to open the Material Chooser
+and pick the desired material from the list.
+
+You can also assign materials programmatically at runtime via
+the :ref:`RenderWorld` Lua API.
+
+Modifying Material properties
+=============================
+
+Once a material is assigned, you can modify its properties dynamically from
+Lua scripts using the :ref:`Material` API.

+===================
+Shading Environment
+===================
+
+The shading environment is a regular :ref:`unit <Units>` that groups
+components controlling global rendering features. Crown uses the properties
+defined in this unit to drive many aspects of scene rendering.
+
+.. figure:: images/shading_environment.png
+   :align: center
+
+   The Shading Environment unit with some of its components shown in the Inspector.
+
+Custom Shading Environment
+==========================
+
+Every level must contain exactly one shading environment unit named
+``shading_environment``. When you create a new level with the :ref:`Level
+Editor`, Crown inserts a default shading environment unit for that level.
+
+Because the shading environment is a Unit, you can edit its components in the
+Inspector and :ref:`save the unit as a prefab<From the Level Editor>` for
+reuse in other levels.
+
+Default components
+==================
+
+Crown provides a set of components commonly attached to the shading
+environment. These components establish the scene base look and control
+post-processing effects.
+
+Global Lighting
+---------------
+
+The Global Lighting component controls the :ref:`Skydome` and ambient light
+contribution:
+
+* ``Skydome Map``: equirectangular projection texture used to render the skydome
+* ``Skydome Intensity``: multiplier applied to the skydome texture to boost or
+  soften its contribution
+* ``Ambient Color``: base color added to objects when direct lighting is
+  absent
+
+Fog
+---
+
+The Fog component simulates atmospheric scattering between the camera and
+shaded objects:
+
+* ``Color``: fog base color
+* ``Density``: overall fog strength; higher values make distant objects appear
+  foggier
+* ``Range Min`` / ``Range Max``: distances from the camera where fog starts
+  and ends
+* ``Sun Blend``: mixes the :ref:`sun <Directional light>` color into the fog
+  (0 = no sun influence, 1 = fog color replaced by sun color)
+* ``Enabled``: toggle the fog simulation
+
+Bloom
+-----
+
+The Bloom component adds glow around very bright parts of the image.
+
+* ``Weight``: blending weight of the bloom contribution (0 = no bloom contribution, 1 = image is replaced by bloom)
+* ``Intensity``: bloom brightness
+* ``Enabled``: toggle the effect
+
+Tonemap
+-------
+
+The Tonemap component maps the renderer's HDR output to the displayable color
+range of the monitor.
+
+* ``Gamma``: no complex tonemapping, only gamma correction
+* ``Reinhard``
+* ``Filmic``
+* ``ACES``

+==============
+Creating Units
+==============
+
+Overview
+========
+
+There are two distinct concepts you need to keep in mind:
+
+- Unit **prefab**: a ``.unit`` resource stored in your project that describes
+  a Unit hierarchy and all its components and properties.
+- Unit **instance**: a concrete instance of that prefab that exists in a
+  running World.
+
+You author and edit prefabs in the tools (Level Editor, Unit Editor and
+importers). At runtime you instantiate prefabs from Lua and manipulate the
+resulting Unit instances.
+
+You do *not* write ``.unit`` files from Lua, and you do *not* author prefabs
+directly from gameplay code.
+
+From the Level Editor
+=====================
+
+Prefabs can be created in a number of ways. Arguably the simplest way  to
+create new Units is to use the :ref:`Level Editor <level_editor>` and then
+save what you have built as a prefab.
+
+1. **Open or create a Level**
+    - Open an existing Level from the :doc:`../level_editor/project_browser`, or
+    - create a new one with ``File`` -> ``New Level``.
+
+2. **Place a Unit in the Level**
+    - Place a new unit with ``Spawn`` -> ``Primitives``, or drag an existing
+      Unit prefab from the Project Browser into
+      the :doc:`../level_editor/level_viewport`
+    - Use the :doc:`../level_editor/inspector` to add or remove components and
+      to fine‑tune their properties
+
+3. **Save the Unit as prefab**
+    - In the :doc:`../level_editor/level_tree`, right‑click the Unit you want
+      to turn into a prefab
+    - Choose ``Save as Prefab...``
+    - In the file dialog, pick a target folder and a unique name, then click
+      ``Save``
+
+The editor will:
+
+- create a new ``.unit`` resource at the chosen location
+- automatically replace the Unit in the Level with an instance of the newly
+  created prefab
+
+From now on:
+
+- editing the prefab will update all instances that use it unless they
+  explicitly override properties or children
+- editing the instance in the Level will create per‑instance overrides
+
+From the Project Browser
+========================
+
+Sometimes you want to start from a blank prefab instead of capturing an
+existing Unit from a Level. You can do this directly from the
+:doc:`../level_editor/project_browser`:
+
+1. Right‑click the folder where you want to create the prefab
+2. Choose ``New Unit...``
+3. Enter a name for the prefab and confirm
+
+This creates an empty ``.unit`` resource that you can then edit:
+
+- by opening it in the Unit Editor, or
+- by selecting any instance that uses the prefab in a Level and clicking
+  ``Open Prefab`` in the :doc:`../level_editor/inspector`.
+
+From imported resources
+=======================
+
+Some importers generate Units automatically as part of their workflow:
+
+- :doc:`../importing_resources/importing_scenes` generates Units for each
+  geometry, light and camera in a FBX file.
+- :doc:`../importing_resources/importing_sprites` generates a Unit prefab,
+  materials and other resources from a spritesheet.
+
+These generated Units appear in the Project Browser like any other ``.unit``
+resource and can be:
+
+- placed in Levels
+- opened and modified in the Unit Editor
+- used as base prefabs for derived units
+
+Spawning Units
+==============
+
+Lua gameplay code never creates new ``.unit`` resources. Instead, it creates
+instances of existing prefabs inside a World. The act of creating unit
+instances at runtime is called **spawning**.
+
+.. code:: lua
+
+   player = World.spawn_unit(world, "units/player/player")
+
+This:
+
+- instantiates the unit ``units/player/player`` into the specified ``world``
+- returns a Unit handle you can store and use from Lua
+
+See :doc:`../gameplay/unit_interaction` for a detailed walkthrough of unit
+handles, Script Component and callbacks.

+Introduction
+============
+
+Units
+=====
+
+Units are the basic building block in Crown. A Unit represents a single
+logical object in the game world: a character, a light, a prop, and so on.
+
+.. figure:: images/units.png
+   :align: center
+
+   A unit imported from a scene, a camera unit, and a unit representing a sprite.
+
+At the most fundamental level, Units are just numeric IDs that identify a
+specific object in a World. Units on their own are empty. You add Components
+to a Unit to give it behaviour and appearance.
+
+Components
+==========
+
+Contrary to some other engines, in Crown all Unit Components are optional,
+even the Transform Component can be omitted. This way you can have purely
+functional Units with no runtime cost.
+
+.. figure:: images/components.png
+   :align: center
+
+   A "light" unit with its transform component displayed in the Inspector.
+
+Units can have any number of components attached to them, but only one
+component per type is allowed.
+
+Hierarchies
+===========
+
+Units can be organised in parent/child hierarchies. This allows the creation
+of complex units from a number of simpler ones. To create a Unit with two
+lights, for example, you will create separate units each with their own Light
+Component, and then link the two together via a Transform Component.
+
+Prefabs
+=======
+
+A unit saved in the Project as ``.unit`` resource is called Prefab. Prefabs
+are a powerful way to reuse units. Prefabs can store not just a single unit,
+but entire hierarchies with all their components and properties.
+
+A prefab inherits all units and components of its base prefab, if any.
+Inherited units and components in the derived prefab can be removed,
+overridden, or complemented with new units and components.
+
+Modifications to a base prefab are automatically propagated to all derived
+prefabs.
+
+The prebab system can be used to implement many popular patterns and
+techniques. The most common use for a prefab is to leverage its inheritance
+system to implement OOP-style behavior; you could have:
+
+- a base ``enemy`` prefab that defines the common geometry, animations and
+  scripts;
+- derived prefabs such as ``enemy_heavy`` and ``enemy_fast`` that override
+  only materials, health values or behaviour parameters.
