Maybe someone can help me. I've been trying for some time now to get Forged Carbon as realistic a texture as possible. Are there shaders that can be combined, or do I have to create an image texture? How do I get some parts to gloss and reflect and others to be matt?

Thank you in advance :)

    $\begingroup$ You could try using an image texture with the principled shader. $\endgroup$ – BlendedCG Oct 20 at 20:55

I'm sure you could do it procedurally, but if you want to use an image texture you could go this way:

  • Unwrap your object with the Smart UV Project mode. Give it a black image texture.

enter image description here

  • Switch to Texture Paint mode, load a forged carbon image texture, choose Brush Mapping > Stencil (Cmd to move, CmdMaj to scale, CmdCtrl to rotate), paint the surface of your object, it will paint over your black image.

enter image description here

  • Mix your image texture with a Glossy node, play with the Glossy value and the Mix factor.

enter image description here

  • If the glossiness depends on the grey value, use the image as a factor in the Mix factor. I don't know forged carbon but you might also want to play with Clearcot, in that case use a Principled instead of a Diffuse.

final

You can use simple "stacking/layering" to make it procedurally.

Basically I've used only Noise Texture with different Scale, Distortion, Detail and different Colour Ramps.

You can add more "layers" of noise to have even better result.

nodes

Note: Noise Texture node is from master build but using currently available in official release changes almost nothing.

  • $\begingroup$ Thank you very much. I will try the layering. How can i add the "lighten" shader and the first option at the Noise Texture (W)? :) $\endgroup$ – NikLeo Oct 21 at 21:11
  • $\begingroup$ @NikLeo Oh darn, which version are you using? I'm building master daily and have just lost track what options are merged into official builds. You can skip 'W' option. Lighten is Color > MixRGB then choose Lighten. $\endgroup$ – cgslav Oct 21 at 21:25
  • $\begingroup$ i´m using 2.8. Thank you $\endgroup$ – NikLeo Oct 21 at 22:03
  • $\begingroup$ @NikLeo it's not that simple any more. We have 2.80 official, 2.81 beta and 2.82 (master) alpha :D $\endgroup$ – cgslav Oct 22 at 0:44
  • $\begingroup$ i´m using v2.80.58. Works really good with the layering 😁. Can I make some of the Noise textures glossy and some matte? $\endgroup$ – NikLeo Oct 27 at 21:53
