I want to apply material to the object. In reality it is fibre cement (or Eternit) of red colour.
I found similar material in Rhino which is beige concrete.
Now, I would like to change beige to red. I tried to use red mask but with no luck.
I would be grateful for help or pointing me to the tutorial where Rhino material is created from the scratch. All what I could find is about using existing materials but nothing about editing them.
