I saw the sharing of the Assassin's Creed Odyssey in GDC. I have a Question about blending multi base materials. Just like this picture.
It layring multi base materials in Substance Painter.
Then import to Game Engine.They used blending Shader to deal with new materials Blending. Like these pictures below.It maybe used vertex color to blending. So Why not blending it in Substance Painter directly.What is the diffenrent of these 2 ways? What is conditions to used them or more properer？
