Glossy problem


Hi, I’m having problems with my glossyness of the glass. In another blender file I don’t have the same problem. I’ve probably changed some settings in this blender file from which I uploaded the picture. I have thickness on the glass so thats not the problem.

Glossy BSDF > set Roughness to 0.000

example from The Cycles Shader Encyclopedia

dont use glass and glossy, use refraction and glossy. if you dont want refraction(which means no light passes) then use glossy and transparent.
