Нашёл вот такой skin shader в сети...Синтаксис:
Используется glsl
Shader "Skin for Unity 3/Bumped Specular" {
Properties {
_Color ("Main Color", Color) = (1,1,1,1)
_SpecColor ("Specular Color", Color) = (0.5, 0.5, 0.5, 1)
_Shininess ("Shininess", Range (0.01, 1)) = 0.078125
_MainTex ("Base (RGB) Gloss (A)", 2D) = "white" {}
_BumpMap ("Bump (RGB)", 2D) = "bump" {}
_RimTex ("Rim ramp (RGB) Fresnel ramp (A)", 2D) = " grey" {}
_WrapTex ("Wrap ramp (RGBA)", 2D) = "black" {}
}

...и всё хорошо, даже замечательно, только он не принимает тени от спут и пойнт лайтов (в Deffered renderer разумеется) Отбрасывать обтбрасывает, а не принимает. Это весьма печально (для меня). Кто нибудь знает почему, и как это исправить?
