Before I can comment on what I would like Carrara to have, I need to know the difference between Carrara 5 Pro and the latest current version.  Basically can you now paint on groups like you could in Raydream 3D.  It's really a pain to ungroup everything, select a part go to the vector room, get the uvmapper, get what you want export it as a .bmp, figure out what is the top, bottom, sides etc, applying the texture, checking the texture, etc.  In Raydream you drew on the whole model, clicked what you wanted and boom it was there.  Jan
