HDRP's Physical Hair for URP

​Documentation

Features

• Tri‑Color Gradient System (No Color Painting Needed)
• A procedural Root / Length / Tip gradient workflow with grey‑hair blending and per‑strand hue variation (mask/strand‑index driven), enabling natural hair color variation without authoring extra color textures.
• Marschner‑Inspired Physical Highlights (R / TT / TRT + Cuticle Control)
• Real‑time Marschner‑style R/TT/TRT highlight structure with cuticle angle and anisotropic strand direction control. Uses pre‑integrated 3D LUTs for azimuthal scattering to achieve stable, high‑quality hair specular response in URP.
• Multiple Scattering Compensation (Dual Scattering)
• Built‑in dual‑scattering term with pre‑integrated attenuation 3D LUTs to compensate energy/color from multiple scattering, improving perceived softness and reducing “plastic” looks, especially in backlit and grazing‑angle lighting.
• Unity 6 + Full URP Rendering Path Support
• Verified on Unity 6 across all URP rendering paths. 
• Includes depth & alpha consistency handling for depth‑priming / prepass scenarios to prevent pass mismatches in complex URP configurations.
• Mobile‑Ready (Mid‑to‑High‑End Devices)
• Compatible with OpenGL ES 3.0+ (GLES3) and designed to be practical on mid‑to‑high‑end mobile hardware.
