Description
-----------

Resource for environment nodes (like :ref:`WorldEnvironment<class_WorldEnvironment>`) that define multiple environment operations (such as background :ref:`Sky<class_Sky>` or :ref:`Color<class_Color>`, ambient light, fog, depth-of-field...). These parameters affect the final render of the scene. The order of these operations is:

- Depth of Field Blur

- Glow

- Tonemap (Auto Exposure)

- Adjustments

Gather ambient light from whichever source is specified as the background.

.. _class_Environment_constant_AMBIENT_SOURCE_DISABLED:

.. rst-class:: classref-enumeration-constant

:ref:`AmbientSource<enum_Environment_AmbientSource>` **AMBIENT_SOURCE_DISABLED** = ``1``

Disable ambient light. This provides a slight performance boost over :ref:`AMBIENT_SOURCE_SKY<class_Environment_constant_AMBIENT_SOURCE_SKY>`.

.. _class_Environment_constant_AMBIENT_SOURCE_COLOR:

.. rst-class:: classref-enumeration-constant

:ref:`AmbientSource<enum_Environment_AmbientSource>` **AMBIENT_SOURCE_COLOR** = ``2``

enum **ToneMapper**:

.. _class_Environment_constant_TONE_MAPPER_LINEAR:

.. rst-class:: classref-enumeration-constant

:ref:`ToneMapper<enum_Environment_ToneMapper>` **TONE_MAPPER_LINEAR** = ``0``

Linear tonemapper operator. Reads the linear data and passes it on unmodified. This can cause bright lighting to look blown out, with noticeable clipping in the output colors.

.. rst-class:: classref-enumeration-constant

:ref:`ToneMapper<enum_Environment_ToneMapper>` **TONE_MAPPER_ACES** = ``3``

Use the Academy Color Encoding System tonemapper. ACES is slightly more expensive than other options, but it handles bright lighting in a more realistic fashion by desaturating it as it becomes brighter. ACES typically has a more contrasted output compared to :ref:`TONE_MAPPER_REINHARDT<class_Environment_constant_TONE_MAPPER_REINHARDT>` and :ref:`TONE_MAPPER_FILMIC<class_Environment_constant_TONE_MAPPER_FILMIC>`.

.. _enum_Environment_FogMode:

.. rst-class:: classref-enumeration

enum **FogMode**:

.. _class_Environment_constant_FOG_MODE_EXPONENTIAL:

.. rst-class:: classref-enumeration-constant

:ref:`FogMode<enum_Environment_FogMode>` **FOG_MODE_EXPONENTIAL** = ``0``

Use a physically-based fog model defined primarily by fog density.

.. _class_Environment_constant_FOG_MODE_DEPTH:

.. rst-class:: classref-enumeration-constant

:ref:`FogMode<enum_Environment_FogMode>` **FOG_MODE_DEPTH** = ``1``

Use a simple fog model defined by start and end positions and a custom curve. While not physically accurate, this model can be useful when you need more artistic control.

.. rst-class:: classref-enumeration-constant

:ref:`SDFGIYScale<enum_Environment_SDFGIYScale>` **SDFGI_Y_SCALE_50_PERCENT** = ``0``

Use 50% scale for SDFGI on the Y (vertical) axis. SDFGI cells will be twice as short as they are wide. This allows providing increased GI detail and reduced light leaking with thin floors and ceilings. This is usually the best choice for scenes that don't feature much verticality.

.. _class_Environment_constant_SDFGI_Y_SCALE_75_PERCENT:

.. rst-class:: classref-enumeration-constant

:ref:`SDFGIYScale<enum_Environment_SDFGIYScale>` **SDFGI_Y_SCALE_75_PERCENT** = ``1``

Use 75% scale for SDFGI on the Y (vertical) axis. This is a balance between the 50% and 100% SDFGI Y scales.

.. _class_Environment_constant_SDFGI_Y_SCALE_100_PERCENT:

.. rst-class:: classref-enumeration-constant

:ref:`SDFGIYScale<enum_Environment_SDFGIYScale>` **SDFGI_Y_SCALE_100_PERCENT** = ``2``

Use 100% scale for SDFGI on the Y (vertical) axis. SDFGI cells will be as tall as they are wide. This is usually the best choice for highly vertical scenes. The downside is that light leaking may become more noticeable with thin floors and ceilings.

Must have :ref:`background_mode<class_Environment_property_background_mode>` set to :ref:`BG_SKY<class_Environment_constant_BG_SKY>`.

This is useful to simulate `aerial perspective <https://en.wikipedia.org/wiki/Aerial_perspective>`__ in large scenes with low density fog. However, it is not very useful for high-density fog, as the sky will shine through. When set to ``1.0``, the fog color comes completely from the :ref:`Sky<class_Sky>`. If set to ``0.0``, aerial perspective is disabled.

The signed distance field is automatically generated around the camera as it moves. Dynamic lights are supported, but dynamic occluders and emissive surfaces are not.

\ **Note:** SDFGI is only supported in the Forward+ rendering method, not Mobile or Compatibility.

\ **Performance:** SDFGI is relatively demanding on the GPU and is not suited to low-end hardware such as integrated graphics (consider :ref:`LightmapGI<class_LightmapGI>` instead). To improve SDFGI performance, enable :ref:`ProjectSettings.rendering/global_illumination/gi/use_half_resolution<class_ProjectSettings_property_rendering/global_illumination/gi/use_half_resolution>` in the Project Settings.

\ **Note:** Meshes should have sufficiently thick walls to avoid light leaks (avoid one-sided walls). For interior levels, enclose your level geometry in a sufficiently large box and bridge the loops to close the mesh.

If ``true``, the screen-space indirect lighting effect is enabled. Screen space indirect lighting is a form of indirect lighting that allows diffuse light to bounce between nearby objects. Screen-space indirect lighting works very similarly to screen-space ambient occlusion, in that it only affects a limited range. It is intended to be used along with a form of proper global illumination like SDFGI or :ref:`VoxelGI<class_VoxelGI>`.

Amount of normal rejection used when calculating screen-space indirect lighting. Normal rejection uses the normal of a given sample point to reject samples that are facing away from the current pixel. Normal rejection is necessary to avoid light leaking when only one side of an object is illuminated.

- :ref:`bool<class_bool>` **is_volumetric_fog_enabled**\ (\ )

Enables the volumetric fog effect. Volumetric fog uses a screen-aligned froxel buffer to calculate accurate volumetric scattering in the short to medium range. Volumetric fog interacts with :ref:`FogVolume<class_FogVolume>`\ s and lights to calculate localized and global fog. Volumetric fog uses a PBR single-scattering model based on extinction, scattering, and emission which it exposes to users as density, albedo, and emission.

\ **Note:** Volumetric fog is only supported in the Forward+ rendering method, not Mobile or Compatibility.

- :ref:`float<class_float>` **get_volumetric_fog_gi_inject**\ (\ )

Scales the strength of Global Illumination used in the volumetric fog's albedo color. A value of ``0.0`` means that Global Illumination will not impact the volumetric fog. :ref:`volumetric_fog_gi_inject<class_Environment_property_volumetric_fog_gi_inject>` has a small performance cost when set above ``0.0``.

\ **Note:** This has no visible effect if :ref:`volumetric_fog_density<class_Environment_property_volumetric_fog_density>` is ``0.0`` or if :ref:`volumetric_fog_albedo<class_Environment_property_volumetric_fog_albedo>` is a fully black color.

\ **Note:** Only :ref:`VoxelGI<class_VoxelGI>` and SDFGI (:ref:`sdfgi_enabled<class_Environment_property_sdfgi_enabled>`) are taken into account when using :ref:`volumetric_fog_gi_inject<class_Environment_property_volumetric_fog_gi_inject>`. Global illumination from :ref:`LightmapGI<class_LightmapGI>`, :ref:`ReflectionProbe<class_ReflectionProbe>` and SSIL (see :ref:`ssil_enabled<class_Environment_property_ssil_enabled>`) will be ignored by volumetric fog.

- |void| **set_volumetric_fog_length**\ (\ value\: :ref:`float<class_float>`\ )
- :ref:`float<class_float>` **get_volumetric_fog_length**\ (\ )

The distance over which the volumetric fog is computed. Increase to compute fog over a greater range, decrease to add more detail when a long range is not needed. For best quality fog, keep this as low as possible. See also :ref:`ProjectSettings.rendering/environment/volumetric_fog/volume_depth<class_ProjectSettings_property_rendering/environment/volumetric_fog/volume_depth>`.

- |void| **set_volumetric_fog_sky_affect**\ (\ value\: :ref:`float<class_float>`\ )
- :ref:`float<class_float>` **get_volumetric_fog_sky_affect**\ (\ )

The factor to use when affecting the sky with volumetric fog. ``1.0`` means that volumetric fog can fully obscure the sky. Lower values reduce the impact of volumetric fog on sky rendering, with ``0.0`` not affecting sky rendering at all.

\ **Note:** :ref:`volumetric_fog_sky_affect<class_Environment_property_volumetric_fog_sky_affect>` also affects :ref:`FogVolume<class_FogVolume>`\ s, even if :ref:`volumetric_fog_density<class_Environment_property_volumetric_fog_density>` is ``0.0``. If you notice :ref:`FogVolume<class_FogVolume>`\ s are disappearing when looking towards the sky, set :ref:`volumetric_fog_sky_affect<class_Environment_property_volumetric_fog_sky_affect>` to ``1.0``.

The amount by which to blend the last frame with the current frame. A higher number results in smoother volumetric fog, but makes "ghosting" much worse. A lower value reduces ghosting but can result in the per-frame temporal jitter becoming visible.

- :ref:`bool<class_bool>` **is_volumetric_fog_temporal_reprojection_enabled**\ (\ )

Enables temporal reprojection in the volumetric fog. Temporal reprojection blends the current frame's volumetric fog with the last frame's volumetric fog to smooth out jagged edges. The performance cost is minimal; however, it leads to moving :ref:`FogVolume<class_FogVolume>`\ s and :ref:`Light3D<class_Light3D>`\ s "ghosting" and leaving a trail behind them. When temporal reprojection is enabled, try to avoid moving :ref:`FogVolume<class_FogVolume>`\ s or :ref:`Light3D<class_Light3D>`\ s too fast. Short-lived dynamic lighting effects should have :ref:`Light3D.light_volumetric_fog_energy<class_Light3D_property_light_volumetric_fog_energy>` set to ``0.0`` to avoid ghosting.

Method Descriptions
-------------------

.. _class_Environment_method_get_glow_level:

.. rst-class:: classref-method

:ref:`float<class_float>` **get_glow_level**\ (\ idx\: :ref:`int<class_int>`\ ) |const|

Returns the intensity of the glow level ``idx``.

.. rst-class:: classref-item-separator

----

.. _class_Environment_method_set_glow_level:

.. rst-class:: classref-method

|void| **set_glow_level**\ (\ idx\: :ref:`int<class_int>`, intensity\: :ref:`float<class_float>`\ )

Sets the intensity of the glow level ``idx``. A value above ``0.0`` enables the level. Each level relies on the previous level. This means that enabling higher glow levels will slow down the glow effect rendering, even if previous levels aren't enabled.
