Question by The-Oddler · Jan 22, 2013 at 12:11 PM · shadershaderlab

Text Mesh with Background

I've been trying to make a very simple shader for 3D text with a background. And I managed to make a working one:

 Shader "GUI/3D Text Shader" { 
     Properties { 
         _MainTex ("Font Texture", 2D) = "white" {} 
         _Color ("Text Color", Color) = (1,1,1,1) 
         _BackgroundColor ("Background Color", Color) = (0,0,0,1)
     }
     
     SubShader {
         Pass {
             Material {
                 Diffuse (1,1,1,1)
                 Ambient (1,1,1,1)
             }
             Lighting Off
             
             SetTexture [_MainTex] {
                 ConstantColor [_BackgroundColor]
                 Combine constant
             }
             
             SetTexture [_MainTex] {
                 ConstantColor [_Color]
                 Combine constant lerp(texture) previous
             }
         }
     } 
 }

So very simple, I have a text colour and a background colour, and I leps between them.

Now, I was wondering if I could simplify this, so it uses only one SetTexture?

Thanks!
