Mesh is deforming in Pose mode without moving the bones For some reason when I switch from Rest Mode to Pose Mose the mesh of the head &quot;squishes&quot; without the bones moving.


Does anyone know why this is happening? I've tried ALT+R,S,G and Clear All Transforms and got no change.

Thank you!

It's because the Stretch Original Length value has been changed... To come back to the default one, click on the X button:
