Random Animation Jitter/Twitch

Hey guys,

I have several shots I've animated using the same model and in almost all of them the head and tongue of the model jitter/twitch around like crazy. The problem is that its pretty random when this occurs, even if I go back to look at the frame it happens on the issue isn't necessarily there and may occur on different frames. Any idea what could be causing this?

I'm using 3ds Max 2013.

Thanks guys

You have to give some more details.

Are you using Biped, Bones, or CAT? Is the Bones, Controllers, or Mesh jittering? Are these morph targets? The more info the better.

Hey Martinez thanks for the reply.

I didn't rig the model (got it off turbosquid) and I'm coming from Maya so my experience with Max animation is limited. The rig is made from bones with helper dummy controllers, the bones and therefore the mesh is jittering. The controllers seem stationary and I don't have any morph targets.

Thanks for the help =)

Is it only happening in viewport playback? have you done an animation preview or a render?

It appears in the view ports, animation previews and renders. If say on a render at frame 23 the tongue is jutting out from the top of the head, when I re render that frame or look at that frame in the view port the animation error may not be there, but may occur at another random frame =S

Jittering rigs are usually caused by trying to animate them far away from world center or from scale issues. Are you working in a very large scene, or do you have your rig far from world center, or attached to something far away?
