This node creates a mask of the voxels inside a camera frustum that are occluded by the objects in the input VDB primitives.
Name(s) of the VDB primitives to operate on. If empty, all VDBs are used. See specifying volumes.
Path of the /nodes/obj/camera object to use as the frustum.
Horizontal voxel count on the camera’s near plane.
Voxel Depth Size
Voxel depth (uniform z-size) in Houdini units.
Depth in Houdini units from the near plane to for the created mask.
Number of iterations to shrink the resulting mask.
Number of voxels to offset the near plane from which shadow voxels are created.
