Substant Paint - Paint the model and export textures

 1. face paint 

Lips was a little tricky, so I found some reference images, and put different layers. One with "0" Roughness on the top. The lips look juice as the reference.

2.Fringe paint. 

In Maya, I have layout the Fringes UV nicely, then bring it to substance paint, otherwise, the fringes are overlayer, and hard to paint

3. Export the textures

Go to Export Textures, and tick all the martials, then export into a new folder.
