How would one go about creating an actual carbon fiber shader?

[Art48]

Hi,

I mean a real one - not just a lit diffuse texture and shiny-shiny. Is there a way of achieving that through shading only? If so how would you go about it? One would need the bumpyness, reacting to light the right way, aswell as a clearcoat.

you need a carbon fiber texture pattern, and matching anisotropy direction pattern, then use that as a base for your carpaint material with glossy anisotropy with ggx, and layer a reflective coat overtop.

Like Dmitry says, Anistrophy map is the technique to use combined with normal map and with clear coat on top.

Some time ago I actually did a short tutorial on carbon fiber material:

It is not perfect, as the shader had to conform to turbosquid guidelines, but I think is a pretty good base

Interesting information, didn't think about the aniso technique, but it makes total sense. Thanks for the pointers!

Are those maps available somewhere to buy/download?

Here are the basic maps I used

Thanks, much appreciated.
