# UnityHairShader Version 9
|
|
This version uses blue noise and alpha to mask dithering to produce significantly better rendering when layering lots of hair strips on top of each other.
|
|
Be aware however, while this is temporally stable, it is not view angle stable -- it must be used with some kind of Temporal Anti Aliasing or Motion Blur.
|
|
|
|
The results are much, much better though.

# UnityHairShader Version 6
|
|
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)
