In V-Ray for Houdini, a Referenced Shader VOP node is now available. It can be used to (as its name implies) reference another node – when you do this, you get the entire shading network up to the node that is being referenced. This means that you could reference your final material and use that as an override material, applying e.g. a Render Stats after it and assigning it to the geometry. This works for any VOP node, e.g. textures, displacement, etc.

  • Disabling the Displacement for an object by saying Use Displacement from Override Material and not supplying any displacement in the override mtl.
  • Changing the Displacement tessellation by applying a new displacement with lower quality settings.
