Just letting people know the vehicle model is very incomplete here. If you try to move the Jet with either the Body bone or Reference bone, the wings will not go with the model as they should. I have already fixed this, as well as finished the skins for the jet which are currently incomplete on this uploaded version.

Cool. Send me the fixed version when you get a chance.

The mouth bones, specifically the upper lip bones, have some of their weighting shared with the lower lip bones, thus stretching them when the mouth is opened.

i checked this out, looks like it happens when you really exaggerate the mouth movement with the lip bones. but when i rotate just the Jaw bone up and down enough to open & close the mouth normally, i don't see it happening as badly.

I can try to fix this, but i'd need to learn up on weighting / rigging (which i need to do anyway since there are many FoC DLC models that don't have the faces rigged at all). As it is right now, we use the skeletal rigging the way it is straight from the game especially since these models have so many robot pieces that need bones.
