help with replicating real woven fabrics

[prima_commerce]

I've been having issues with realistic renderings of some of the more complicated/intricate shiny and rough woven fabrics. I've attached photos of an example fabric (sorry for the low quality).

From farther away I can make a material that simulates the fabric but up close it just loses all realism. The issue mostly being the clumped "fuzz" type of effect - large strands clumped in certain patterns. I know textures can be applied to fur density for example but strands still don't "stick" together quite the same.
I have tried with fur and displacement but it either loses details or it looks too fake (scale and softness of the fur being a big part of the problem). I've also considered doing it with enmesh but it's usually a pretty small weave so it lacks the randomness and softness on a bigger surface.

I've tried searching on the internet but no help, there's lots of instructions on getting certain types of fabrics (satin, velvet etc.), but my work is usually connected to a specific fabric. Can somebody help or point me in the right direction about tackling these kind of fabrics or at least researching further?

Hi @prima_commerce, I would ask sirio76. He has made some amazing fabrics. You can check out his work here. https://forums.chaos.com/member/213686-sirio76 and here https://www.3dtutorialandbeyond.com/store/

I’ll answer tomorrow morning

You have several options depending on what level of detail you need. A good texture and a proper shader should be enough to produce nice results in most conditions. If you need a closeup then you can build a large enough pattern to reproduce enough surface variations, and coupled with an hair shader with proper scattering and color randomization you will be able to get very accurate results. Of course the second option is more time consuming and you'll also need UV on your mesh. You may also get good results using Vray fur coupled with a Vray Hair shader, should be enough unless you need very close detail.

On this project you can see a couple details using both enmesh and fur:

Thank you for the replies. I was hoping there was some sort of established "trick" or set of steps to doing it that I just wasn't getting. I guess I'll have to just try some options until I find the one that looks right to me. I'll definitely give enmesh/spline combination another try.

If maps were supported, then more randomisation would be trivial, as it is with regular scatters.

In my head that seems doable. Is that a possible upgrade devs?
