Adding Material

In the MAT pane, create a PxrMaterialBuilder, dive inside, and create a PxrVolume BxDF

Assigning Material

Drag your PxrVolume VOP to the Material parameter of your volume OBJ.


For deformed volume, velocity and density must be wired using PxrPrimVar.  This is because 'v' in VDB is a built-in variable.
