I am exporting to FBX, but the Eye Occlusion and Tearline parts don't have any of the matching Expression blend shapes.
They do have their depth blend shapes, and of course the body has the Expression shapes.
Looking for a workaround:
If I export an OBJ with the option to keep Facial Expressions, the extra eye parts are exported and correctly deformed…, but, if I try to import that OBJ as a custom blend shape those eye parts are ignored. I get the custom slider and the eye and body morph as expected, but no custom shapes on Eye Occlusion or Tearline.
Have I missed a step that loads the matching blend shapes onto the eye parts?
