Physbones will snap animated bones to a unexpected pose when activated. I've tryed with all parameters, even limiting all movement and it still snaps animated bones. video of a test https://youtu.be/OBhCWrbE9BU
update: this snapping happens when the phys bone component is added to a empty at the avatar's root for organization 4rth pic, ther's only one animation playing with one frame posing the tongue bones.
If the component is added at the bone doesnt snap in unexpected ways 3rd picture.
2nd Update :
I've isolated the issue to just one animation, animates position rotation and scale of the second bone in the chain affected by the phisbone component, snaps it to another position when the physbone is enabled.
I can provide the minimal proyect with just the avatar and the two animations that do the blep and reset it.
