I have a model with several materials that I used to render a scene in Cycles. I wish now to put that model on SketchFab, but I need to bake my textures into single files for it. I successfully baked Roughness, Diffuse and Normals, but there's no option to bake metallic. How can I get this done?

Plug the metallic input into the roughness input of the principled shader and then bake the roughness map (texture) of the texture plugged in. I hope it will work...
