Modulated vertex color shader

Unity Engine
1

I think I’ve come across this earlier but i cant find the post / source again. What I’m looking for a is modulate2x vertex color shader. As to gain both over-brightening and shadows from as single vertex color channel.

Help please :slight_smile:

You want that with actual in-game lights? Or all the lighting is already baked, and there should be no real-time lighting?

If all lighting is already baked, then something like this shader would be good (that’s a stripped down version of BakedVertexColorLighting, with 2x modulation added):

Shader "Baked Vertex Lighting/Modulate 2X" {
Properties {
    _MainTex ("Base (RGB)", 2D) = "white" { }
} 
SubShader {
    Pass {
        BindChannels {
            Bind "Vertex", vertex
            Bind "TexCoord", texcoord
            Bind "Color", color
        }  
        SetTexture [_MainTex] { Combine primary * texture DOUBLE }
    }
}
}

It does nothing fancy, just binds in vertex colors, and does a modulate2x (in D3D terms) of texture and vertex color.

Cheers, works great :slight_smile:

Hi~This is surface Shader~
How can I implement modulate2x in Vertex and Fragment Shader by " + " , " - " ," * " ," / ".
Is this just simple " *2 " with final color to return??
