if you make a cube it works great but when you are working on the final details of a complex project the bugs increase greatly. Save often or you'll be sadly dissapointed. Then there are the artifacts produced by the bad renderer in animations that make you go crazy. Animations are limited in this program to say the least. Enough said Vue5 will be better and will be a sidesidegrade to justify the high cost of the same program with the same materials and objects. ;-)
