There is no need for double uv sets.
I just use mask layers to hide teamcolor where i dont want it to be. So it's manual thingy. Luckily this thing wont have that much teamcolor area anyways.
Pretty much same thing what i am doing here with colors.
Semi procedural/seamless textures are there only to help me with progress i still have to do detailing and stuff manually.
I can use seamless normal maps for plating etc.
Using 10 different plating normal maps. Overlap em for different results.
And then use mask layers to hide some parts of them which i dont like.
Final finish will be done manually of course.
