I have had a better look at the ear and theres not a lot of polygons to make a tiny hole from.

Attached is a morph file , it needs a bit more work to smooth it out but its ok for a test.

copy the file , rename it as an zip ,extractthe obj  and use the load morph from parameters panel for the HEAD of V4. You should get a small hole in the left lobe .   If thats what you are after I will try to clean it up.

• file is vertices only *
