Hi Berg Looks like you simply have 2 conflicting influences on your eye_orient_target locator's rotation channels (the incoming values from your GUI translations, as well as the parentConstraint intended to have the locator follow the translations & rotations of the chestJnt)
The easy solve would be: 1) After you create your locator (line 39), you should group the locator 2) Then in line 20, parentConstrain the locator's group node rather than the locator. This should allow you to have the GUI drive the rotations of the locator, while the chestJnt drives the rotation & translation of the locator's group. That should resolve the conflict and solve the popping. Hope that helps Cheers C On Thursday, April 25, 2013 1:24:10 PM UTC-4, Berg Jones wrote: > Hi.
