Multi Shaders for Same Material 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 ?

Picture 2 - The Faces i applied my ash/metal metarial



Picture 3- Node setup i used to mix metal and ash texture with help of an alpha image
Instead of one shader (Glossy), use a Mix shader node that is fed by the Glossy node and a Diffuse node, and plug that alpha image into the mix factor of the mix shader to control where the shader type is.
