Hmmm... that scene still crashed when I moved to the final frame (frame 30).

However, 1.0.0.27 is definitely showing some performance improvements.

Enough in fact that I was able to move to frame 11... at which the Genesis figures were actually in pose... and then I was able to save each one as a cr2, without Poser crashing.

I've already reconstructed the rest of the scene (all the non-Genesis elements) and proven it doesn't crash without them in it. So I guess I will try adding them back into that reconstructed scene and see if that crashes once more... or not.
