by using a second UV channel we were able to drive most of the parameter to modify the hair inside of unreal engine. See the next image for more details
The first UV Channel drives most of the usually used maps such as normal roughness metallic etc.
The second UV Channel drives the base anisotropy, root/tip gradient and the strands normal which gets added in the engine.
demonstration of subsurface scattering support. For more details see the next Image.
The Subsurface Scattering Shader Model don't support Anisotropy from the Default Lit Shader. To mix it im blending both shader models with a float of 0.99 and multiply anisotropy by 100.

Back in 5.0 the epic hair shader model was broken especially for solid models. So we used as a workaround this shader which use material attributes and mixing the relevant shading models together.
