Human skin pores and micro-relief

Generate tileable PBR detail maps of human skin: pores of varied size, the polygonal furrow network stretched along tension lines, aged creases, melanin and redness variation, freckles and oily or dry roughness, in several skin tones. Use as tiling detail on characters, faces, hands and creature skin.

Limits to consider

This is tiling micro-detail, not a full skin material: there is no subsurface scattering, no colour map of a face or body, and no layout by region (nose, forehead, cheek). Pores sit on a jittered grid, furrows are borders of warped anisotropic cells and creases are ridged noise, all stylized approximations of real dermal structure. Skin tones are artistic presets, not measured; use the albedo as a tint or overlay over a character's own colour. Relief is small, so the normal map carries most of the effect. Occlusion is a blurred-height estimate.
