Hmmm as i can see many people started using Bryce before started using Vue. Im one of them. Bryce is a great 3d app but havent been updated for awhile and that leeds to some limitations comparing to other 3d programs. I used to post my art here on renderocity and while i was browsing to other apps i found Vue. Long story sort by seeing what it can do from other artists and checking the official site - e-onsoftware i decited to get it.
I havent regretted it at all.. well up to this time im writing these lines :)
