I have both Carrara5 Pro and Vue5 Infinite. I've done some very nice work with V5I. However, considering C5Pros excellent modeling tools, and superior terrain tools (not to mention excellent surface distribution -- similar to V5I), I'm using C5Pro more and more -- just too many bugs with Vue. For example, plants get distorted with the latest Vue patch! I just discovered that a few days ago, and reported it with 7 screen captures. It seems like e-on fixes one set of problems, then new ones crop up due to the "fix." I think e-on used too much Vue4 code in creating V5I -- V5I should have been a clean code base. Carrara has been wonderfully bug free.
