I found some bugs that werent listed on the faq- Camera 1 Keyframe Limits: Carrara gets confused when Camera 1, your active camera, has more than about 15 keyframes. Once you get past thoat point, you cannot move/rotate/dolly/pan/bank the camera until some keyframes are deleted. Render Failed Part 2: You listed a Render Failed Bug, I noticed it also occurs in some booleans. Sometimes the bool will work, sometimes not. Seems random. Saving Movies: Sometimes, when saving QT movs, Carrara bugs out and crashes. However, the mov file is intact, but any changes in the scene file are lost. Sometimes this crash can be avoided by going to the assemble room, saving, and then tryting to save your movie. But that doesn't always work. *Note-These may or may not be Mac specific. These all occured on my iMac DVSE '99, 256 mb ram. Nebula Supernova Studios
