I am trying to implement the material on the object, such as the picture below, without the texture image. I've looked for a function called "Bump Node" to implement the material, but I'm not yet proficient in this, so it's hard to solve the problem. Is there a way to implement a material without a texture image only in a geometry configuration? Or, there is other ways for solve this problem?
*I'm going to make translucent material. So I don't think it's right to use texture images.
