blending materials with sliders

You will find a very simple shader with blending posted here:

http://answers.unity3d.com/questions/392616/fade-shader-one-texture-fades-in-the-other-fades-o.html

Typically these shaders use _Blend as a variable so doing a Google search on "Unity3d _Blend shader" will produce hits.

I've never used it, but you might take a look at: Material.Lerp().

Hi,

Thanks for responding! I found the blend 2 textures shaders on the Wiki site

http://wiki.unity3d.com/index.php/Blend_2_Textures.

I've attempted to try to modify it to incorporate more that 2 textures. I was able to add a third but unfortunetly it will only blend the tex01 and 02 but not the third. I'm a new to writing shaders. Not sure what I did wrong here.

Here's what I modified.

 Shader "Blend 3 Textures" { 
 
 Properties {
     _Blend01 ("Blend01", Range (0, 1) ) = 0.5 
     _Blend02 ("Blend02", Range (0, 1) ) = 0.5
     _MainTex ("Texture 1", 2D) = "" 
     _Texture2 ("Texture 2", 2D) = ""
     _Texture3 ("Texture 2", 2D) = ""
 }
  
 SubShader {    
     Pass {
         SetTexture[_MainTex]
         SetTexture[_Texture2]
          
         { 
     ConstantColor (0,0,0, [_Blend01]) 
     Combine texture Lerp(constant) previous
         }    
         
         SetTexture[_Texture2]
         SetTexture[_Texture3]
         {
     ConstantColor (0,0,0, [_Blend02]) 
     Combine texture Lerp(constant) previous
             }
 
     }

Any help would be greatly apperciated.

Thanks!
