Yes, loading your metalnessmap into the diffuse slot (or specular slot) is a good work around for the time being. Just make sure you go to the options (gear icon) and turn off sRGB for that texture. Re: color value, that is working as intended. The color picker value multiplies on top of the albedo input, to allow for…
Ok, great to hear! Thanks for the answer. A somewhat cumbersome workaround for now is to create a second set of materials for all the source meshes where only the metalness map is plugged into the albedo channel. This way I can transfer the metalness map from my high to my lowpoly anyways. As for the slightly darker albedo…
