Anyone knows how to make good looking fabrics like these?

I struggle a lot making any good looking fabrics, velvet shader is not even able to produce good looking velvet, cloth shader is slow to render hard to control and still has limited usage.

So I'm left with principled or matte material and on both of those I can't get any backscatter effect. For example in cycles you have fresnel node which you can even multiply and use as a mix factor between materials, but in luxcore those don't exist so I tried mixing velvet and disney but everything I come up with looks like vomit...

EDIT: Part of the problem might also be that mix material and velvet have both broken bump mapping

for cloth glossy shader can be used too info from wiki
with using multibounce

Not only that this doesn't provide enough backscattering but due to the fact that glossy is broken, it even darkens at glancing angles (Disney doesn't have this problem)

Maybe combining Disney and velvet, but then mix material has broken bump mapping an velvet itself probably too.
On top of that luxcore doesn't have a fallof/fresnel node that could be used to force mixed material to appear based on facing normals.

Not sure what would be the best approach, but fstorm results are just mind blowing.
