UnityHairShader

A hair shader originally built for the sine.space virtual world, designed and built for Unity3D's PBR rendering system.

Leverages the Anisotropic Rendering released by Matt Dean availible from https://github.com/Kink3d/AnisotropicStandardShader - and incorporates features from Alan Zucconi's implementation of EA's Frostbite Fast Translucency algorithm (GDC 2011).

Quick Summary:

• Anisotropic highlights
• PBR-ish. Has option to tweak/remove unrealistic fresnel highlights.
• Optional variant with Normal Map support
• Double Sided (optional - delete the first pass if you dont need it)
• Works with Shader Model 3.0 (Normal Map variant requires SM 4.5, but will fallback to SM 3.0 variant)

Notes:

• Is going to be kinda heavy. Performance seems OK here, but could probably do with optimisation.
• We render the lower pass using alpha testing versus blending; this fixes a host of issues with ordering; it's a little smelly, but it works better over all.

Shows up as 'Sine Wave/Modern/Adam's Hair Shader 1.0' (Plain variant) and 'Sine Wave/Modern/Adam's Hair Shader 1.1' (Normal variant)
