Transparent Self-Illumin shaders?
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.
Well, I'm needing all those both the gloss and the illumitation map... As well the alpha...
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
}
}
}
}
}
The builtin "Unlit/Transparent" shader does the same, except that it's not tintable.
The ideal (if you ignore the lack of Gloss, that is) would be having a similar shader, but with a alpha cutoff float, where 1 would be totally oppacc and 0 would be invisible...
