This complements the existing Ellipsoid and Box local fog shapes. This can be used to represent a light cone coming from a SpotLight.

|
[FogVolume]s are used to add localized fog into the global volumetric fog effect.
|
|
Performance of [FogVolume]s is directly related to their relative size on the screen and the complexity of their attached [FogMaterial]. It is best to keep [FogVolume]s relatively small and simple where possible.

Sets the size of the [FogVolume] when [member shape] is [constant RenderingServer.FOG_VOLUME_SHAPE_ELLIPSOID], [constant RenderingServer.FOG_VOLUME_SHAPE_CONE], [constant RenderingServer.FOG_VOLUME_SHAPE_CYLINDER] or [constant RenderingServer.FOG_VOLUME_SHAPE_BOX].
|
|
[b]Note:[/b] Thin fog volumes may appear to flicker when the camera moves or rotates. This can be alleviated by increasing [member ProjectSettings.rendering/environment/volumetric_fog/volume_depth] (at a performance cost) or by decreasing [member Environment.volumetric_fog_length] (at no performance cost, but at the cost of lower fog range). Alternatively, the [FogVolume] can be made thicker and use a lower density in the [member material].
|
|
[b]Note:[/b] If [member shape] is [constant RenderingServer.FOG_VOLUME_SHAPE_CONE] or [constant RenderingServer.FOG_VOLUME_SHAPE_CYLINDER], the cone/cylinder will be adjusted to fit within the extents. Non-uniform scaling of cone/cylinder shapes via the [member extents] property is not supported, but you can scale the [FogVolume] node instead.
