Transparent Self-Illumin shaders?

Questions & Answers
1

Hi there! So I need to know if any of the self-illumin shaders allows to make the objects transparent. I’m trying to make a cloaking device like effect, and so I would need to give the information that his ship is cloaked, while allowing the player to see it…

Any ideas?

Thanks in advance…

The Unity builtin shaders reserve the alpha channel for the gloss map, that’s the main reason there are no builtin transparent equivalents.

If you don’t need a gloss map, and also don’t really use the illumination map (except to mark the whole ship as “being there” by assigning a white texture (or none at all)), you can just use the builtin Unlit/Transparent shader.

Otherwise you’d have to write or find a shader which has alpha, gloss, and/or illumination as separate textures.

You can use this shader…

Shader "Unlit/AlphaSelfIllum" {
    Properties {
        _Color ("Color Tint", Color) = (1,1,1,1)
        _MainTex ("SelfIllum Color (RGB) Alpha (A)", 2D) = "white"
    }
    Category {
       Lighting Off
       ZWrite Off
       Cull Back
       Blend SrcAlpha OneMinusSrcAlpha
       Tags {Queue=Transparent}
       SubShader {
            Pass {
               SetTexture [_MainTex] {
               		constantColor [_Color]
                  	Combine Texture * constant, Texture * constant
                }
            }
        } 
    }
}
