🧵 multiple materials/single UV. Blender/Substance.

Welp, what is the best way to deal with this:

I made a model that needs different materials. All parts are UVed together (to a single 4096x4096 image). Now, I need the different materials to map to that single UV layout (it has to be a single UV).

Think of a flashlight: the outside plastic/inside chrome/glass lens all need to go into a single texture.

Currently, I assigned the different parts of the mesh to different materials, problem is when I take that into substance, it creates three different 4096^2 textures.

How can I tell the programs "hey, use 1/4 of the image for the chrome, 1/4 for the glass, 1/2 for the plastic"? Cutting and sewing the images in photoshop sounds like a bad way to do it.
