Likes: 1) The render engine - fast and realistic, what more could you want? 2) The shader tree structure - I at least find it intuitive and easy to make complex shaders 3) The interface - I can't believe this still attracts review comments like "Awkward rooms metaphor" - if you even think of changing it, then how about offering a simple preference for "Carrara Classic" or "Normal confusing 3D program"? 4) The new animation tools 5) General stability and reliable patches Would-likes: 1) Improved particle system (interacting with other scene elements, "intelligent" particle behaviours, built-in "point at" modifier, perhaps even some particleIllusion-style sprite setups. 2) Subpoly displacement in the shader tree/render engine. It's the only place where the high-end renderers (and - ulp! - even Poser 5) have an edge over the Carrara engine. 3) Volumetric shaders (granted we have Primivol now, but I have lots of occasions where I'd like to put a volumetric effect onto a normal object...) 4) Don't want Julien to lose out (and I have already bought Replica), but the functionality of Replica is one plug-in that really should be built-in (ideally as a modifier). 5) Some kind of scripting/formula system to open up custom behaviours, deformations, and shaders to the masses. Again not to do any plug-in makers out of work, but there are as many custom requirements as there are Carrara users, and there will never be a plug-in for everything... (For instance, I've never seen anyone offer extra deformations as a plug-in...)
