I have version 2.40a and 2.37a. I made a scene and decided to try some of the new features in 2.40a. The new features work great. But when I tried to animate it, the animation came out choppy and the shadows didn’t seem right. So I tried to render the scene in 2.37a and now the scene is completly messed up. So:
Is there a terrible backward compatability problem in the two versions. (The only real new feature I used is the shapes option.) Is there a problem when you save in 2.40 and reopen in 2.37. Are there still some render problems with 2.40 that still need to resolved.
