unity自发光透明shader

unity自发光透明shader

这本来是一个glass的shader，但是我发现也可以用到自发光+透明，这两个脚本都是unity文档里面的。呵呵~~~

Shader "Custom/AlphaSelfIllum" {
Properties {
        _Color ("Main Color", Color) = (1,1,1,0)

        _Emission ("Emmisive Color", Color) = (0,0,0,0)
        _Shininess ("Shininess", Range (0.01, 1)) = 0.7
        _MainTex ("Base (RGB)", 2D) = "white" { }
    }

    SubShader {
        // We use the material in many passes by defining them in the subshader.
        // Anything defined here becomes default values for all contained passes.
        Material {
            Diffuse [_Color]
            Ambient [_Color]

        SeparateSpecular On

        // Set up alpha blending
        Blend SrcAlpha OneMinusSrcAlpha

        // Render the back facing parts of the object.

        // than the front-faces.
