Houdini generates a new vector field called scatter when you apply the new Pyro post process node. This makes octane shift the entire volume. If I delete the scatter field, it goes back to normal
the vdb file for testing

It also happens in Octane standalone.
Also, the new Standard volume shader isnt working in Houdini nor in Solaris.
