Hi, Ben, You probably want to post this as a new post rather than a followup to this thread; you will get more answers that way. I switched from Bryce5 to Carrara in April. Not familiar with RD5, though, so can't answer abuot RD. Carrara can be used to create objects for Bryce. But unless you do landscapes, you'll probably switch to Carrara, it is much more capable. marc
