DETAIL SKIN WITH UV PROJECTION
Detailing skin is a tedious job. Since the popularity of scanned data has risen, artists tend to project displacement maps and colours using software like Mari. However, projecting a 2D image on a 3D model requires projecting from multiple angles and needs blending fixes for every projection. Furthermore, the projected displacement map does not match the projected diffuse map, since they can’t be projected simultaneously.
It becomes apparent that 3D space might not be the best place to make such projections. Instead, matching the model by its UV with the 2D scanned data can project a near-perfect and continuous texture. Of course, this is not the old-school UV snapshot plus Photoshop method, but even that is worth some research in this 3D-oriented texturing era.
The basic idea is simple. First, make a flattened version of the model that looks exactly like its UV, and overlap it with another flat plane with the texture attached. Second, tweak the flat UV model so that its shape matches the texture. And finally, bake the texture from the plane to the UV model. Since the UV model shares the same UV as
