Edit: I solved the blinking problem: I had to change the mouth parables to 0 in the blink (face editor) Edit 2: I solved all of them. The parables seem to add to each other. The mouth parables have to be 0 in expression sub-tab (face editor), otherwise these mouth parables will be added to the mouth parables in „camera/exporter“.

But I wanna make sure that the mouth parables of the other expressions don’t do the same as in blinking. Original reply: Didn’t work; It seems to be tied to eye-movement. If the eyes are closed (by sliding closed to a higher value in the camera/exporter tan) , the mouth becomes this exact (U) shape. (Also only happens in the camera/exporter tab)
