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 lightsource.

Attributes
| Name |
Description |
|---|
| Grid Width/Hieght/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

Typical Node 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 Modifier |
Links all transform properties to the input node. |
Null |
| Target Node |
Always faces the x-axis towards the inputs anchor point. |
Null |
| Local Transform Override |
Override the transformation values of the node, relative to its parent. |
