|
|
A node used to add local fog with the volumetric fog effect.
|
|
|
|
Description
|
|
-----------
|
|
|
|
``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 :ref:`FogMaterial<class_FogMaterial>`. It is best to keep ``FogVolume``\ s relatively small and simple where possible.

|
Sets the size of the ``FogVolume`` when :ref:`shape<class_FogVolume_property_shape>` is :ref:`RenderingServer.FOG_VOLUME_SHAPE_ELLIPSOID<class_RenderingServer_constant_FOG_VOLUME_SHAPE_ELLIPSOID>`, :ref:`RenderingServer.FOG_VOLUME_SHAPE_CONE<class_RenderingServer_constant_FOG_VOLUME_SHAPE_CONE>`, :ref:`RenderingServer.FOG_VOLUME_SHAPE_CYLINDER<class_RenderingServer_constant_FOG_VOLUME_SHAPE_CYLINDER>` or :ref:`RenderingServer.FOG_VOLUME_SHAPE_BOX<class_RenderingServer_constant_FOG_VOLUME_SHAPE_BOX>`.
|
|
|
|
\ **Note:** Thin fog volumes may appear to flicker when the camera moves or rotates. This can be alleviated by increasing :ref:`ProjectSettings.rendering/environment/volumetric_fog/volume_depth<class_ProjectSettings_property_rendering/environment/volumetric_fog/volume_depth>` (at a performance cost) or by decreasing :ref:`Environment.volumetric_fog_length<class_Environment_property_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 :ref:`material<class_FogVolume_property_material>`.
|
|
|
|
\ **Note:** If :ref:`shape<class_FogVolume_property_shape>` is :ref:`RenderingServer.FOG_VOLUME_SHAPE_CONE<class_RenderingServer_constant_FOG_VOLUME_SHAPE_CONE>` or :ref:`RenderingServer.FOG_VOLUME_SHAPE_CYLINDER<class_RenderingServer_constant_FOG_VOLUME_SHAPE_CYLINDER>`, the cone/cylinder will be adjusted to fit within the extents. Non-uniform scaling of cone/cylinder shapes via the :ref:`extents<class_FogVolume_property_extents>` property is not supported, but you can scale the ``FogVolume`` node instead.

Sets the shape of the ``FogVolume`` to either :ref:`RenderingServer.FOG_VOLUME_SHAPE_ELLIPSOID<class_RenderingServer_constant_FOG_VOLUME_SHAPE_ELLIPSOID>`, :ref:`RenderingServer.FOG_VOLUME_SHAPE_CONE<class_RenderingServer_constant_FOG_VOLUME_SHAPE_CONE>`, :ref:`RenderingServer.FOG_VOLUME_SHAPE_CYLINDER<class_RenderingServer_constant_FOG_VOLUME_SHAPE_CYLINDER>`, :ref:`RenderingServer.FOG_VOLUME_SHAPE_BOX<class_RenderingServer_constant_FOG_VOLUME_SHAPE_BOX>` or :ref:`RenderingServer.FOG_VOLUME_SHAPE_WORLD<class_RenderingServer_constant_FOG_VOLUME_SHAPE_WORLD>`.
