How do you make a Fuzz map?

Hi

One thing I'd love to learn is how exactly to make a Fuzz map for clothing. I did a Google search, but nothing useful has come up. It looks to be something useful to include to help make my clothing look more like clothing. To include some, well, fuzz lol. What is the best workflow for this? Is it just a case of adding XGen hair? Making very small and thin hairs covering the surface and baking it down to a map? What are some of the common workflows?

Thanks

For unreal engine, cloth is just a 0-1 from not fuzzy to fuzzy and fuzz color is the color of the fuzz (usually the same color as the cloth but desaturated and lighter).

There's also roughness, which changes the extent of the fuzziness.

I've done a lot of work with the Sheen extension in glTF, to create velvet, satin, and other fuzzy surfaces. https://github.com/KhronosGroup/glTF/blob/main/extensions/2.0/Khronos/KHR_materials_sheen/README.md 

An example model you can play with:

If you click on the "Display" link it'll load a live demo. 

I can explain this a bit more if it helps.

"How do you make a Fuzz map ?" suggests that you already have a material/shader ready to receive a such map, and that you only need to figure out, somehow, how to create this image map.

Is this actually the case ? Or, is your question more along the lines of "How do you make things look fuzzy ?"
