I have an ashtray model(picture1). I picked some faces(picture 2) and applied an material for ash and some part of metal under it. i mixed two textures with MixRGB node and used black/white image as alpha to clean around ash so that the metal part seems. But in the end, i want my ash part not glossy(diffuse) and metal part glossy. How can i achieve it ?
