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.

Parameters

Attributes

These properties control the core behaviours of the node.

Parameter	Details
Grid Width/Height/Depth	Control the resolution of the voxel grid along each axis.
Visible	A keyframable toggle for controlling whether the renderer is active or not.
Colour	A colour tint applied to the whole volume.
Depth Alpha Scale	Scales the density of the volume.
Shadow Absorb	Scales the density of the volume with respect to shadow propagation.
Shadow Scatter	Controls how deeply shadows propagate through the volume.
Shadow Area Scale	Scales the rectangular area where shadow propagation will be computed.
Shadow Tint Colour	Control the colour tint for the shadows.
Generate Colours	Use the colours generated by other nodes in the procedural system.

Inputs

Name	Description	Typical Input
Procedural Root	Use 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
Lights	Lights to use for shadow propagation	Directional Light
Bounding Box	Bounding box within which voxels will be generated and raymarched	Bounding Box
Transform Modifiers	Apply the transforms of another node to this node.	Null
Target Node	Modifiy the rotations of the node to always direct the z axis towards the input.	Null
Local Transform Override	Apply the transforms of another node to this node, relative to its parent.	Null
