I have been using both Bryce and RayDream since the versions of Bryce 3D and the $99 version of RayDream Studio 5 (Ray Dream 3D). I still use RDS 5.5 because of the ability to import Poser 3 files and Carrara does not. Bryce 3 (and Bryce 5) is so user friendly you can actually generate decent picture w/o having to consider your entire contents of picture. RayDream Studio is the older incarnation of Carrara. The latter two tools take more time to master due to the consideration of thinking about not only just putting your model in the scene but also the context in which your model exists, its surroundings, the lighting. The degree of control you have over your image seems daunting to the newbie 3Dphile like me. I get my copy of Carrara 3 on Monday! Laters Yall, Form Validation Error
