Multi Layer Specular
Hello All.
I am working on a carbon fiber texture for an upcoming automotive project at work. I have made a decent weave patter in photoshop for the base color and it looks pretty good. The problem I am running into is with the specular part. Most carbon fiber has a gloss coat that’s really shiny on top of the fiber weave but the weave itself also sparkles. I created a specular map for the sparkles in the fiber but I can’t figure out how to set up the specular property to have multiple layers.
Any suggestions would be greatly appreciated!
Thanks in advance,
Russ

Specularity maps would normally go in the specular color channel in C4D, but it sounds like the sparkly effect of the fibers might show up better if you put your “sparkle map” in the luminescence channel and still have your specularity effect the overall weave. Hard to tell really without seeing an example.

Probably want to use Lumas in the Luminance channel, or use it in a layer shader along with the bitmap in the color channel.

Thanks for both of your suggestions. I will give them a shot & see what happens.
