Here's what I do to handle this. Basically, I set up key frames at every 30 frames (1, 30, 60, 90, 120) AFTER editing the position changes. I start off with 90 frames and just the 1st and last frames are keyed (this allows looping but can be optional). I make my next changes at frame 30, then set that as a key frame. THEN I copy this keyframe to frame 31 (this keeps the interpolation from overshooting). I make my next changes at frame 60, make key frame, copy to frame 61. You get the idea. When I'm done I have an animation to be proud of (I think)...... Krel
