I finally got my boxed version of C5. I haven't had a chance to really get into it yet, but have found some pros and cons already. The good stuff: 1. Being able to pan and zoom using mouse & keyboard - couldn't do that in C4. 2. The new displacement shader. 3. Ambient occlusion. Also I noticed that the lighting seems to be calculated and rendered faster than in C4. 4. Lots of new landscapes in the scene wizard. The not-so-good stuff: 1. The new interface - the overall look of it is kind of cheap-looking. I liked C4's interface better. Also I don't like how the different windows can't be undocked. 2. The vertex modeller - I had high hopes for this one, but Carrara's vertex modeller is as infuriating as ever. Silo and Blender are easier for me. 3. The new shader tree is a little bit confusing, but I'll figure it out eventually. I wish I had been able to download the C5 demo and play around with it, but I can't download large items due to a very slow dial-up connection. If I had, I probably wouldn't have upgraded to C5.
