In Carrara, those functions are found in render room under G-buffers. No options for grunge, shadows, occlusion or any lighting effects though. :-/ You can fake some of those using the G-buffers and object positions with Photoshop but it's not like working with RPF and Combustion. Hopefully, those will find their way into a future version of Carrara. But for the entry level price of Carrara, I guess I can't complain too loudly. Nothing wrong with wanting a program that does everything and doesn't break the bank? Right? :-D Mark
