The idea is to have the ability to realistically simulate "small pile" / "short pile" / "low pile" fabrics such velour or velvet in the Fabric Mtl.
The suggested solution is to add an additional section in the same material that would imitate small hairs and their brdf using the same parallax, for example
With the following controls:
Length
Width. Together with the general tiling this would allow for the overall regulation of the pile density
Angle relative to the surface (mappable using a black and white map). 0.0 would correspond to the pile direction coinciding with the surface normal, 1.0 - crushed pile, 90 degrees to the surface normal. With this parameter we could regulate how much the surface will shine.
Pile rotation along its own Z-axis (mappable parameter by analogy with Anisotropy rotation in a regular CoronaPhysicalMtl). The original rotation value can be set using a object's UVs as in the case of anisotropy.
