unity ignoring some bones during animations

So i have a rig which i exported with its mesh to unity, converted to humanoid, made the avatar and everything works fine, except in one of the animations the character is supposed to smile, but unity completely ignores the mouthlowerbone (or in the humanoid setting as jaw bone), i can move the bone in the editor, but when the game is playing and the animation is called, everything works except for those bones.(mouth upper is ignored also).
Any idea how to fix this?

 

Do both the model rig and the animation rig have the jaw bone assigned properly? That should be all it takes.

 

im using the same rig for the model and the animations. it's on the same FBX that i imported from blender. so i only configured it once. im not sure if i should configure it somewhere else.

 

If they're both part of the same FBX it should definitely work. Maybe you could take a look at it in the animation window, but I can't think of anything else that could be wrong.

 

sorry to revamp this thread . please were you able to solve this problem , i am having the same issue .

 

Yes!
It was on the quality settings, the "Skin weights", increasing this solved the problem!

 

thanks alot for the response .
i was able to solve it aswell though was a different problem. i had to enable a bones under the mask under the animation tab in inspector.(inspector /animation/ mask/humanoid/transform )
