Imported animations deforming mesh strangely

Hey I imported a new animation for my character and for some reason the head is melting away when it plays. It is a punching animation, and other animations do not do this on the character, does it look like a skinning problem or an export problem?

Looks like you might have some messed up weighting issues. Is one animation exceeding the max influences?

I’m a bit of noob I’m not sure exactly what that means, do yo mean in 3ds Max or in Unity? Just a little background info, I had this same animation working correctly but it was backwards, so I had to flip it in 3ds max and then when I re-exported it from max the deformity is happening. Where can I check for the max influence?

Problem resolved. If you go to Quality under the inspector, and select 4 bones it fixes this problem. Does anybody have any experience with how much this will bog down performance?

Usually it’s not a big deal unless you have lots of skinned characters.
