THe way I see things is that I have two seperate rendering environments - which can't see each other's shaders/textures/ etc. I don't think that I can use any materials from the Maya renderer unless I have some kind of translation tool (such as MayaMan, I think). I am not sure that all this is worth it but, I am still learning... It seems that PRMan can't do some things (like fur).... Renderman seems faster than the Maya Renderer and I think Networking is 'easier' with Renderman - I still can't figure out how to network render w/ only Maya!!! Cheers.
