I've had that problem (duplicating motion paths) lot of times... That's why I stopped using Carrara's animation features but for the most simple things... I'm afraid that Carrara's animation tools (specially motion paths) s..k (sorry...) I think they are aware of it and the next version of Carrara will have better animation tools (or at least that's what they've told) I still love Carrara and use it for stills but for animations I would recomennd you to buy the $99.00 3DToolkit 2.5. It's a very good productions quality program. Its a very fast Phong renderer I belive, No real reflections (which you can fake with maps) , transparency yes. It's the little brother of Universe ( Kind of like Carrara and Carrara Basics) You can export models from Carrara and import them there. Or vise versa (hope I spelled that right.. ) It has a NURBS modeler that is somewhat different that Carrara's but It complements it quite nicely. I specially like the boolean operation and beveling options.... I go back and forth between the two and like that workflow a lot. In the animation departement you have Bezier motion paths that work Beautifuly (like you would expect Carrara's to do) F. Curves editor, deformers, etc etc Also check the other DV garage's products. They usually work with the Toolkit but almost all of them can be used with other 3d products. Really can't go wrong with that 99 investment if you are serious about animation.. :) Hope I could help you a little with a different opinion Good luck with that fjv
