Visemes gets stuck help?

[PoppinOrange]

this model is a low poly and has drawn mouths for planes hiding inside the head and appears forward from speaking. everythings correct in blender and unity and redid few times but it gets broken in VRC gameplay

the frame gets stuck on the open mouth after speaking and idk how to solve that. when i resetted the avi it doesnt fix it, when i rejoined the world it did fix it? but it goes back to being broken after speaking. other lipsync frames does show more btw its just the one frame gets in front after not speaking… please help!!

That’s what happened to me! After I open my mouth to speak and then turn off the mic, my mouth opens to a certain gag pattern and doesn’t shut up completely! Someone please tell me what to do!

I’ve had this exact issue before on an avatar. The only way I figured how to fix this is to swap the SIL viseme to something else, it’s a little jank but it worked for me, hope this helps!
