Satin is a bit tough to work on bump+sheen alone, it is somewhat reproducible but the lack of detailed maps, proper UVs won't make it look nice in most angles, so you'll have to resort to using a custom fresnel.
Thus you can apply a falloff curve to sheen itself in order to emulate more satin surfaces, this works great and the effect is more subtle than diffuse+falloff and seems to react better with scene lighting overall.
For silk-velvet, sheen alone is enough, comparison: https://corona-renderer.com/comparer/RugNph
Thx for the reply, I mainly work with fabrics and have made hundreds of attempts to recreate complex shaders such as velvet, satin, silk, wool and so on, including growing millions of fibers in Ornatrix and combing them and then using CoronaHairMtl to get proper anisotropy reflection for the correct velvet, and basically I can create any texture in substance designer e.g.
But at the moment, if I understand everything correctly, we have no way to get the correct direction of the anisotropic reflection along the single fabric thread using height maps or normal maps, no matter how detailed they are, we can only fake it using the anisotropy rotation map.
And we also don't have a geopattern to mimic the real fabric structure. So I'll probably have to tweak the faloffs again and wait for the next release :D
PS
please guys, pay attention to the implementation of coating, which we wrote about above. let it be possible for coating to smooth the surface, creating mirror-like glossy coat with displaying the height details of the surface lying below, as Bormax mentioned here
New material is really great! Thank you!
The Clearcoat layer is the thing I was missing for very long time, nice to get it now. Some idea came to my mind about it.
Now the Base bump affects the Clearcoat layer and Clearcoat bump gives possibility to Add bump to this layer. Would it be nice (if it's possible) to have kinda lock between Base bump and Clearcoat bump in order to imitate the bumpy surface covered by the polished transparent layer of lacquer? Something like on attached picture where I've created the geometry of the covering layer and assigned different material to the inner and covering surfaces.
According to this idea if the Lock is active Base bump affects the Coatlayer, if it's unlocked only Clearcoat layer's bump affects the Coat layer.
PPS
and maybe it is worth lowering the metalness map slot below the others, because now I habitually attach base color or diffuse to it as it is the first in the list :D
