I've made photogrammetry of a head, and via some sculpting i made model
of a head. Then i did retopology, and apply diffuse texture to a lowpoly
model. In general i'm satisfied by result. (Later i'll correct some
mistakes in Photoshop, and in Blender texture painting mode)
Here is my preview of texture (real size 8k).
I'm
planning to use it in game engine, so i want to add some maps
(specular, AO, bump, e.t.c.). All tutorials i have seen based on
painting face textures from scratch. I don't need it, because i already
have "basic texture".
The questions are:
1. Is it possible, to
make additional textures (specular, AO, bump, e.t.c.), based on my
duffuse texture, for using them in game engine with marmoset? If yes, point me please
to tutorial according by point.
2. What additional maps i must make, for making this head realistic?
If there is a another software, to make this task (Substance painter???), point me please to this software.
