How to make a glass material having a dotted design and lines? I am new to blender so I don't know much procedural materials. Recently, I started to create a model of my own house in blender and I don't know how to make a glass material look like my window's material. I tried to add roughness to glass but it still having a nice and smooth surface. Rather I want a dotted glass material and with some designing lines. I am sharing an image too.   Please refer picture and help me.
