I am kind of new to Blender and have been looking for this a few days now and can't seem to find out so I ended up here.
I have a base object on which I have scattered stars. For the coloring of the stars I have set up the following nodes to give it random coloring:
- Object info (Random) --> Colorramp (I have set up my colors) --> Principled BSDF (Base Color) --> Material Output.
Now I want to add metallic colors and these have a different roughness than my normal colors. So I tried to add in a new ColorRamp node with my metallic colors and a new Principled BSDF with a lower roughness setting followed by a Mix Shader to add in both BSDFs.
But the outcome gives me random roughness on all colors. I only want the specific colors to look metallic...
