Progress so far. No problems encountered.
My maps. The cavity map has pixels at the nose. I expected that already. Maybe I should have gone for the 4K maps, instead of the 2K map size. But I also experienced in previous projects, 4K is slow on my machine.
Have fun, go render something.
*I now see, the nose has a strange artefact. This part has many problems. Mirroring went wrong, Normal map ray distance problems, Shrinkwrap problems … *
