Hello all, I've been fighting back and forth between RDS5.5 and Cararra, knowing that I wanted one of them. In the end, I picked up RayDream (mostly for its compatability w/Poser). Been working with it and while cluttered its a great app! =) I have 2 questions. 1) What is a good place to start finding solid tutorials for RDS5.5? 2) Given that I got RDS for under $200. How can I upgrade to Cararra now? (This way I can have the best of both worlds) Thanks all!! Falcon
