I have found Bryce to be one of the most difficult and cryptic 3d programs I've ever attempted to use.  I don't like it's GUI or having to shift through countless dialogue boxes to make changes.  I perfer Vue to Bryce for Poser import, it seems to import poser figures better without me having to mess with material setting to make them look right.  Vue plants and trees also are much more realistic, the ecosystems are to die for and now Carrara replicates in a way similar to ecosystems.   Every time I try to do a Bryce scene I've given up in frustration 99% of the time.  Perhaps it's just me but I can't relate to Bryce, I want to like it, but I've had too much frustration with it to continue to try to be productive with it right now. 

I can appreicate the affection that 3D old times have for the application, but it wouldn't hurt my feelings at all if Daz took all the features currently avaialble in Bryce and put them into Carrara 7 and merged the applications.  Still there enough room in the 3D universe for alternative landscape rendering applications, so I hope for the sake of those affectionately in love with Bryce that they continue to develop it.  Under Corel there was little improvement, Daz seems to be aggressively pursuing the Bryce market.
