Ah, ok. Thanks for the response. I get what you are saying and will try to further my own understanding of how to implement this script and scripting in general, and I appreciate you taking the time to clarify things. I am surprised that there isn't more of a demand for a more refined tool to revert RS materials. Do you know of any other approaches to achieving this? I realize this outside the realm of this forum an appreciate any input you might be able to provide.
