Thanks so much for solving the issue! The reference image was simply placed too closely to the model.. oops 🙂 – it really cut away that part of the ear (the timing of that error is fascinating, though, given that it coincided so closely with the creation of a mask at that spot of the ear…luckily I don’t start all over to model the head now, thanks so much for your help and saving me from that headache @everyone ;-).
