This script was a request I received a while ago.
the goal was to press one button and convert all lights and materials from RenderMan to redshift, there wasn't any shader involve in this video but if there was it would change them too, renderman shaders are very different than redshift so transfering attributes was a bit tricky,
I was working on a more advanced version of this with the option to switch between vray-redshift-Renderman-Arnold with a single click for the unofficial updates for Maya, but currently, I have to pause other projects because of Easy Terrain update which was supposed to be released on September but during final tests i found a critical error and now i have to remake all of it again so hopefully after i finished the update i can continue other scripts.
