this problem with max drives me absolutely mad. :banghead: :argh:
I'm using Set Key mode for character animation.
My problem is that when I play the animation with Set Key mode activated, every single time slider motion is stored into undo buffer and this behaviour basically owerwrites (and clears with unvonted undo data)the undo buffer.
So when I'm fine-tuning my animation, and alter some pose for example, than if i forget to turn off the Set Key Mode (and it's very impractical to turn it off and on like mad...)and play the animation to see the changes, undo is cleared (overwritten with time slider's motion) and I can't undo the changes I made to animation (character pose).
Is there any solution for this behaviour?
