I've got both. Based on your comments, Carrara will be a better choice simply because you can do more with it on the modeling side including modifying your existing models if you want or simply creating new ones or new plants. Also, Carrara's replicator allows you to quickly populate landscapes with a varity of vegitation without creating huge files. Carrara's clouds are pretty nice to. Finally, Carrara renders substantially faster than Bryce. That's worth it's weight in gold. Bryce still holds the edge in ease and variety of atmospheric effects although Carrara is no slouch in that department. If your only goal is to do outdoor scenes with pre-made content, you may want to check out the latest Vue6 - it's awesome in it's atmosphere effects and renders waaay faster than Bryce. Vue's spectral atmospheres are to die for! Mark
