Well, I don't use Carrara but only RayDream Studio. There are several things you can't be made under RayDream - and Carrara, I think. Indeed, NURBS and MetaNurbs models can't be done under RayDream/Carrara, but other modelling techniques like the Coons' and Gordon surfaces, and more common ones are much better under Amapi. For example, I had to do a boolean substraction to make a wheel. RayDream did the operation very slowly, and the final object was really high-weighted in vertices (several thousands !) ; under Amapi 4.15, the boolean operation was faster and the wheel only weighted 356 vertices ! Amapi is a "companion modeler" and should be used for its quality. If you want to have an overview of the complementarity between RayDream/Carrara and Amapi, have a look at my web site, in the Tutorials section. Fabien
