Figures I animate will get weird flutters on them like the skin is unstable or something. My first thought was that the animating lights were doing it, but I don't think so. Anyone else come across this and how do I stop it. Even Zygote's Michael gets the flutter. I appreciate the advice.

yes i have seen this before. it is a result of the interpolation of movements. what i do is try to isolate the "frame" where the flutter appears and adjust the associated joints. An example was a top that flutterred at the shoulder. I stepped through the frames until i saw the "flutter". At that frame i adjusted the shoulder and coller joints on the top or you can re-conform the top at this point. I fit is a body joint then you will have to adjust the "flutter" joint a few degrees. Be warned that this may result in another flutter somewhere along the animation.

The other possibility is that you are over stretching a limb with inverse kinetics on....try getting all your key frames set, then turn off inverse kinetics before animating. Scarab
