Ok, The soft shadows improvement is MASSIVE! I personally believe that's the most important change from 2 to 3 and it makes a huge improvement. I've been able to generate renders in 3 that I would consider impossible previously (not exaggerating here folks). HDRI rocks. The GI renderer is better altogether and produces some really great stuff. Object selectable 3D Aura is another personal fave that was added making some of my stuff possible versus painful post production. The plant editor is new for 3. It's very cool. Plants are hard without it unless you've got some other tool. I think it is a BIG improvement over 2 but note, a lot of the changes might be considered subtle for some. Lots of the these improvements are bent on pushing Carrara to produce heavier hitting images (which it does). Some of our previous Lightwave converts away from Carrara are back here I've noticed. That should say something. -Kix
