Hello, what if I have one object with five materials on it and I want to bake them all at once on one texture.
How do I bake all of those materials into one texture at once?
Because right now I have to bake texture for each material, that’s like five different textures and five bakings, that takes very long.
You can’t, broadly speaking. You can mix the materials together with Mix Shaders, but this won’t preserve the integrity of each one. If you’re just going for three different black and white materials, you can bake them into the RGB channels of a single image, but I don’t think that’ll help you here
As long as there no overlap between those materials, you can add the same texture to all materials and bake it in one go.
