Why Is This Geometry Distorting When Infinty Used?

[david-mattock]

HI, Ive done a simple run cycle for a character, this goes from frame 1 to frame 16 and looks great when i play it back from frame 1 - 15 continously within the maya stage.

so I then set infinity to be on and add a make my timeline a few hundred frames long so it loops and play it back, then on random frames it is suddenly completely distorting my geometry !? why is this happening , please help

the first 16 frames play back with no distortion at all?
Ive attached an image

Thanks

looks like your bones got flipped. did you use a pole vector constrain? if not perhaps you will have to manually key those attributes as well on the ik handle.. hope that helps
