The light is attenuated by distance and this attenuation can be configured by changing its energy, radius, and attenuation parameters. \ **Note:** When using the Mobile rendering method, only 8 omni lights can be displayed on each mesh resource. Attempting to display more than 8 omni lights on a single mesh resource will result in omni lights flickering in and out as the camera moves. When using the Compatibility rendering method, only 8 omni lights can be displayed on each mesh resource by default, but this can be increased by adjusting :ref:`ProjectSettings.rendering/limits/opengl/max_lights_per_object`. \ **Note:** When using the Mobile or Compatibility rendering methods, omni lights will only correctly affect meshes whose visibility AABB intersects with the light's AABB. If using a shader to deform the mesh in a way that makes it go outside its AABB, :ref:`GeometryInstance3D.extra_cull_margin` must be increased on the mesh. Otherwise, the light may not be visible on the mesh. .. rst-class:: classref-introduction-group Tutorials --------- - :doc:`3D lights and shadows <../tutorials/3d/lights_and_shadows>` - :doc:`Faking global illumination <../tutorials/3d/global_illumination/faking_global_illumination>` .. rst-class:: classref-reftable-group Properties ---------- .. table:: :widths: auto +------------------------------------------------+----------------------------------------------------------------------+-------------------------------------------------------------------------------+ | :ref:`float` | :ref:`omni_attenuation` | ``1.0`` | +------------------------------------------------+----------------------------------------------------------------------+-------------------------------------------------------------------------------+ | :ref:`float` | :ref:`omni_range` | ``5.0`` | +------------------------------------------------+----------------------------------------------------------------------+-------------------------------------------------------------------------------+ | :ref:`ShadowMode` | :ref:`omni_shadow_mode` | ``1`` | +------------------------------------------------+----------------------------------------------------------------------+-------------------------------------------------------------------------------+ | :ref:`float` | shadow_normal_bias | ``1.0`` (overrides :ref:`Light3D`) | +------------------------------------------------+----------------------------------------------------------------------+-------------------------------------------------------------------------------+ .. rst-class:: classref-section-separator ---- .. rst-class:: classref-descriptions-group Enumerations ------------ .. _enum_OmniLight3D_ShadowMode: .. rst-class:: classref-enumeration enum **ShadowMode**: :ref:`🔗` .. _class_OmniLight3D_constant_SHADOW_DUAL_PARABOLOID: .. rst-class:: classref-enumeration-constant :ref:`ShadowMode` **SHADOW_DUAL_PARABOLOID** = ``0`` Shadows are rendered to a dual-paraboloid texture.

A value of ``0.0`` will maintain a constant brightness through most of the range, but smoothly attenuate the light at the edge of the range. Use a value of ``2.0`` for physically accurate lights as it results in the proper inverse square attenutation. \ **Note:** Setting attenuation to ``2.0`` or higher may result in distant objects receiving minimal light, even within range. For example, with a range of ``4096``, an object at ``100`` units is attenuated by a factor of ``0.0001``. With a default brightness of ``1``, the light would not be visible at that distance. \ **Note:** Using negative or values higher than ``10.0`` may lead to unexpected results. .. rst-class:: classref-item-separator ---- .. _class_OmniLight3D_property_omni_range: .. rst-class:: classref-property :ref:`float` **omni_range** = ``5.0`` :ref:`🔗` .. rst-class:: classref-property-setget - |void| **set_param**\ (\ value\: :ref:`float`\ ) - :ref:`float` **get_param**\ (\ ) The light's radius.
