|
A region that contributes to the default volumetric fog from the world environment.

[FogVolume]s are used to add localized fog into the global volumetric fog effect. [FogVolume]s can also remove volumetric fog from specific areas if using a [FogMaterial] with a negative [member FogMaterial.density].
|
|
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.
|
|
[b]Note:[/b] [FogVolume]s only have a visible effect if [member Environment.volumetric_fog_enabled] is [code]true[/code]. If you don't want fog to be globally visible (but only within [FogVolume] nodes), set [member Environment.volumetric_fog_density] to [code]0.0[/code].

<member name="material" type="Material" setter="set_material" getter="get_material">
|
|
The [Material] used by the [FogVolume]. Can be either a built-in [FogMaterial] or a custom [ShaderMaterial].
|
|
</member>
|
|
<member name="shape" type="int" setter="set_shape" getter="get_shape" enum="RenderingServer.FogVolumeShape" default="3">
|
|
The shape of the [FogVolume]. This can be set to either [constant RenderingServer.FOG_VOLUME_SHAPE_ELLIPSOID], [constant RenderingServer.FOG_VOLUME_SHAPE_CONE], [constant RenderingServer.FOG_VOLUME_SHAPE_CYLINDER], [constant RenderingServer.FOG_VOLUME_SHAPE_BOX] or [constant RenderingServer.FOG_VOLUME_SHAPE_WORLD].
|
|
</member>
|
|
<member name="size" type="Vector3" setter="set_size" getter="get_size" default="Vector3(2, 2, 2)">
|
|
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 size. Non-uniform scaling of cone/cylinder shapes via the [member size] property is not supported, but you can scale the [FogVolume] node instead.
