I created a Cheese Shader.
People loved it, but some thought it looked like other things like old apple inside, french fries, butter and so on. I have here my first five- the Cheese Shader, butter shader, French Fries, Sweet potato Fries and a second Cheese Shader :)!
All done procedural in Blender Cycles.
