I will, like many here, upgrade both. I use whichever one is best for the project at hand. They have both, in the past, had their strengths and weaknesses. I expect that to continue. I find Bryce's material editor an almost impossible creation. Other's work with it with no problem. I prefer Vue's water while others I respect like Bryce. I like the texture renders I get from Vue of my Poser people much, much better than Bryce. On the other hand, for some reason, I do like Bryce's atmospheres. Others believe atmospheres are where Vue rules over Bryce. So, you see, much depends on personal likes and dislikes. I am assuming you asked your question here since a similar question in the Bryce forum is likely to get you shot if you disagree with the purebred "Brycers" on any topic at all. ;-) I think you will find many, many Vue-Bryce mongrels in these forums. ;-) Take care and Godspeed.
