HI, I am facing a strange vertex-lock effect when trying to edit a 'smile' target on a character's face. Other bSh and targets have been made around the shoulder, arms, etc, and suddenly a new blendShape with a single target is impossible to edit. Of course the 'edit' button is made red on the right target and every envelopes turned up to 1. Anyone having an idea what is going on? Thanks in advance.
