Omnidirectional light, such as a light bulb or a candle.
</brief_description>
<description>
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 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.

<member name="omni_attenuation" type="float" setter="set_param" getter="get_param" default="1.0">
The light's attenuation (drop-off) curve. A number of presets are available in the [b]Inspector[/b] by right-clicking the curve.
</member>
<member name="omni_range" type="float" setter="set_param" getter="get_param" default="5.0">
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.
[b]Note:[/b] [member omni_range] is not affected by [member Node3D.scale] (the light's scale or its parent's scale).

Shadows are rendered to a dual-paraboloid texture. Faster than [constant SHADOW_CUBE], but lower-quality.

Shadows are rendered to a cubemap. Slower than [constant SHADOW_DUAL_PARABOLOID], but higher-quality.
