ive grown rather decent in c4d with only minor problems here and there, however i think i wanna try to catch up to pixar. i have access to maya,and own c4d r12, so the question is... should i make the switch? i want optimum photorealism and i want complete unfettered control over every aspect in my models, but i dont wanna lose things like motors, connectors, and cloners (omg theyve made everything soo much easier as far as animation shortcuts) but i guess the big question is professionalism. and maya has renderman. PIXAR'S renderman. so here it is, can c4d mess with maya in that aspect? i know about cineman and how its supposed to be a renderman substitute, but mine must be messed up cuz everytime i try to use it i get a 'cannot find prman.exe' but thats another story. since ive never used it, i gotta go with ppls input cuz i cant see it for myself. and if possible, can someone show me something fantastic outta cineman? i havent gotten to the export process which is another issue separate from this, but i just dnt wanna plow ahead with cinema and find out maya was where it was at the whole time
I think Maya uses a plugin bridge to renderman, so does C4D. On the modelling front - nothing gives you unfettered control over every aspect of your model - there would not be maya to mudbox and maya to zbrush workflow tutorials (etc.) if that were true, but what you use as the main modeller depends on what your pipeline is going to be and your personal taste. Use them both if you have access to both.
As Brian said, Cineman is just a bridge to renderman compliant renderers. I think for most people that's not something you want to mess with, as they tend to be much more difficult to deal with. You really have to know something about scripting to get anything out of them, in my limited experience.
