The Hanmen shaders and textures are unique. Here's a quote from his own discord post when he recently released the shader for free, where he mentions DHH/Graphics:
If you try to use his shader with DHH, even a non-Hanmen skin texture will look gray or black. But the Hanmen's SSS skin texture (the missing mod in question) is somehow tied in with the Sub Surface Scattering setting in the Graphics mod, so Graphics is even more important for the texture than for the shader. But realistically they all work together, and the results are impressive once it's dialed in. MrWrongtubes has recently posted a few great examples in the card sharing thread:
