An Omnidirectional light is a type of [Light3D] that emits light in all directions. The light is attenuated by distance and this attenuation can be configured by changing its energy, radius, and attenuation parameters.
[b]Note:[/b] 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 [member ProjectSettings.rendering/limits/opengl/max_lights_per_object].
[b]Note:[/b] 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, [member GeometryInstance3D.extra_cull_margin] must be increased on the mesh. Otherwise, the light may not be visible on the mesh.
Controls the distance attenuation function for omnilights.
A value of [code]0.0[/code] smoothly attenuates light at the edge of the range. A value of [code]1.0[/code] approaches a physical lighting model. A value of [code]0.5[/code] approximates linear attenuation.
[b]Note:[/b] Setting it to [code]1.0[/code] may result in distant objects receiving minimal light, even within range. For example, with a range of [code]4096[/code], an object at [code]100[/code] units receives less than [code]0.1[/code] energy.
[b]Note:[/b] Using negative or values higher than [code]10.0[/code] may lead to unexpected results.
The light's radius. Note that the effectively lit area may appear to be smaller depending on the [member omni_attenuation] in use. No matter the [member omni_attenuation] in use, the light will never reach anything outside this radius.
