Well, I finally recieved my upgrade from RDS 5.5 to Carrara, happy to report that I didn't have to pay full fare! Installed on a G3 350/OS 8.6 at work & played with it for about 15 minutes, seemed to work OK. Installed at home on a G3 233/OS 8.1, and every time I try to "render" the program crashes. Probably some extension conflict that I'll have to hunt down (so fun!). Can't save as Painter riff format but havn't played with it long enough to tell anything else. The window layouts & function are more similar to Infini-D then RDS. I'll reserve judgement 'till I've played with it some more. One thing they should have put on the disk are some of the animated examples from Infini-D. Shows some powerful effects that can be acheived with the particle system like blowing smoke & fireworks that were very well done.
