Ok, I did reset the settings before but not the additional “clean install option”. So I did both again, made a new file with the fox, and ran the steps as before. It looks slightly better (a bit less of the ears missing), but it’s still happening.
The version I have is 10403 (Steam).
I’ve taken the liberty to upload the fox scene for debugging (please let me know if it makes sense to upload the other one as well, since it’s arguably worse. I just haven’t retried with that one yet). You might notice I’m a bit in a hurry
