Has anyone figured out how to make a truly photorealistic velvet material? If so, I'd love to know how!
Yeah, I've been able to get the sheen pretty correct, but it still doesn't look like an actual fabric (like the one on the booth).Eric Nixon 20170610100005 wrote: ↑Fri May 04, 2018 11:54 pmI haven't used velvet in a render, it never came up, but I made a quick basic material here, a good starting point maybe. Looks a bit odd on the simball shape.
The material would look better if the 'fibers' were oriented 'combed' in various directions, but I'm not sure how to create the anisotropy angle-map with a matching normal map.
Its a shame the forum upload attachment seems broken....., EDIT: I think its attached now. The missing map was just a high contrast noise map.
The material is 2 bsdfs in the base layer, 1 additive bsdf layer for the fine hairs, all bsdf use r2, the base colour bsdf gets darker at the r90, each bsdf gets a bit smoother with a higher nd, and the r2 effect gets stronger. This is just mixed by eye, and could be mixed better by studying references.
