I am attempting to morph the characters face to create expressions, and following a tutorial am using HS2PE and the blend shapes menu sliders to do so. However, none of the sliders for the mouth on the menu seem to alter anything on the character. The sliders can affect the eyebrows and eyes, just not the mouth. I don't know where to begin looking for the cause of this issue, and nothing I've been able to look up online seems to discuss this particular issue. If anyone has experienced this before or would have any ideas any help would be much appreciated.
