Volume Generator

Volume Generator

Renders a procedural system as a volume through voxels.



Method #

Renders a procedural as a translucent volume. This node is suitable for creating cloud-like effects. It first voxelises the procedural and then renders it by raymarching. It is able to cast shadows within the volume in the direction of a light source.

This node only supports Directional Light nodes.


These properties control the core behaviours of the node.

Grid Width/Height/DepthControl the resolution of the voxel grid along each axis.
VisibleA keyframable toggle for controlling whether the renderer is active or not.
ColourA colour tint applied to the whole volume.
Depth Alpha ScaleScales the density of the volume.
Shadow AbsorbScales the density of the volume with respect to shadow propagation.
Shadow ScatterControls how deeply shadows propagate through the volume.
Shadow Area ScaleScales the rectangular area where shadow propagation will be computed.
Shadow Tint ColourControl the colour tint for the shadows.
Generate ColoursUse the colours generated by other nodes in the procedural system.


NameDescriptionTypical Input
Procedural RootUse a Procedural Root as an input, so the renderer is treated seperately from the roots transforms. In this case, the renderer itself would be connected to the scene Root node.Procedural Root
LightsLights to use for shadow propagationDirectional Light

Transform ModifiersApply the transforms of another node to this node.Null
Target NodeModifiy the rotations of the node to always direct the z axis towards the input.Null
Local Transform OverrideApply the transforms of another node to this node, relative to its parent.Null
