_SpecGlossMap with Standard (Roughness setup)

Hello,

I have a custom editor window that creates a material and then binds textures.

Code (CSharp):

1. Material mat = new Material(Shader.Find("Standard (Roughness setup)"));
2. mat.SetTexture("_SpecGlossMap", roughness_tex);

Everything is ok for albedo, normal, occlusion, detail normals EXCEPT for _SpecGlossMap ! the texture does not appear and is not applied at shading, and no error poping :/

I'm using Unity 2017.3.0f3, would really need some help on that !

 

"Standard (Roughness setup)" does not have a specular gloss map.

you need to use "Standard (Specular setup)"
