@yukinoh1989 Yes, I used this course @silentheart00 mentioned as a base for carbon fiber. Thought in 2.8 EEVEE gives a bit different result so you will have to play a bit with components and settings. And later watch the wood shader tutorial, it will blow of your mind completely 🙂
This carbon shader should be a good base for a cloth too but still I haven’t got a good result. If someone manages to make a good cloth please share how you achieved it.
