 			Sets the size of the [FogVolume] when [member shape] is [constant RenderingServer.FOG_VOLUME_SHAPE_ELLIPSOID] 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].

 			Sets the [Material] to be used by the [FogVolume]. Can be either a [FogMaterial] or a custom [ShaderMaterial].
