Corel spent a lot of effort in getting the render quality to equal some of the more expensive packages. They've cleaned up some things, stabilized code, and added the trees. i'm not sure why they added the trees the way they did... i've found them to be kind of weird. Given the kind of competition they face, i'm not sure i could have made better decisions on what to upgrade. Vue seems to have sacrificed the ability to do some basic good 3d modeling with primitives for the vegetation thing. Oh well. There are inexpensive models and Plant Studio, really. B5 does pep up their terrain editor, mat editor (now there's a USER mats category!), and lighting editor. And they have soft shadows--not to be sneezed at, friends, as the harshness of Bryce lighting renders was quite the achilles heel.
