Houdini 20.5 Nodes VOP nodes

Vex Volume Procedural VOP node

This procedural will generate a volume from a CVEX shader.

Since 11.0

Each export from the shader will be bound to a corresponding vex surface shader parameter, if it exists. If the bounding box is not specified for the procedural, a unit bounding box will be used.

Parameters

Main

Shader

The CVEX shader which is used to define the volume. Each parameter export from the shader will be bound to a corresponding VEX surface shader parameter (if it exists).

Octree Divisions

Represents the voxel divisions of the volume primitive used for rendering.

IFD Bounds

Bounding Box

The bounding box controls let you specify a bounding box for the referenced geometry. Only when this bounding box is “on screen” will mantra load the referenced geometry. You can set Bounding Box to No bounding box required, in which case mantra will always load the references geometry regardless. You can also specify the bounding box by referencing the SOP’s bounding box in the SOP Bounds parameter.

SOP Bounds

The geometry whose bounding box you want to reference.

Min Bounds

The minimum bounding box dimensions, when setting explicit bounds.

Max Bounds

The maximum bounding box dimensions, when setting explicit bounds.
