Testing with a 3D scanned model from https://blenderguru.us17.list-manage.com/track/click?u=ac8ab0580c321574fe178a646&id=cce6dfd5a1&e=cca79833e1. Materials modified from the basic material that comes with it, and a poor image from a time appropriate programme (and making it poor took some effort).
But, just playing.
