Title: how make Speaker kevlar fiber material ?
Post by: remydedez on 2022-11-12, 16:01:27

Hello, Everyone, someone of you know How to Make This Kind of matériel because I Tried to Make It But result isn't what I expect.

Thanks for your help ;-)

you need a diffuse map for the structure, and i would also paint a fitting anisotropy direction map (used with slight anisotropy effect on).
then probably a slight bump etc.

this can be done in photo shop, maybe also out of reference images, start painting one small tilable part, then copy to generate a bigger surface with slight variations (or probably quite easier via c4d plugins for generating such tiles structures)

Some PBR materials you can find on the web for wicker might get you close, then some adjustments. The other thing I tested was using Corona Pattern. Here's a screenshot of what I set up. I made a simple repeatable set of cylinders and use the Pattern tool to apply them to the speaker's surface. I've never used this tool before, and I found it a little tricky if you're not good with UVW mapping, which I am not. I was able to rotate things and get it close. If I took my time and made a proper weave section, this would look even better. I added a little bump and displacement stretched out in one direction for the surface effect, but the anisotropy direction would also work too.

Hope this helps. Here's a Chaos quick starter video on the Pattern tool:

Thanks! I think a Chaos scan material might be a good option here. If you fine tune some settings I think you will get the look you're after. :)

thanks beanzvision but we must have chaos scan to use it right ?
