2 channel Self Illuminating Shader request.

I just don't get shaders or any sort of programming (I'm using Playmaker). So I'm just going to be cheeky and ask for a shader as I cant find what I'm looking for.

http://docs.unity3d.com/Documentation/Components/shader-SelfIllumDiffuse.html

What I want is something like the self illuminating shader, a Main Colour but with 2 seperate textures with alpha channels, so still with 2 textures, not ending up with 4. Then I want the textures to multiply together.

So, any help?

 

Well I gave it a go and got this far but how do you get the colour tint to work?

Code (csharp):

1. Shader "Custom/IlumBlend" {
2.  
3. Properties {
4.     _Color ("Color Tint", Color) = (1,1,1,1)
5.     _MainTex ("Texture 1", 2D) = ""
6.     _Texture2 ("Texture 2", 2D) = ""
7. }
8.  
9. SubShader {
10.     Pass {
11.         SetTexture[_MainTex]
12.         SetTexture[_Texture2] {
13.             combine texture * primary + previous
14.         }      
15.     }
16. }
17.  
18. }

 

I downloaded the shaders and opened up the Illumin diffuse to edit.

But it's still not right. The textures don't blend properly.

Code (csharp):

1. Shader "IllumBlend2" {
2. Properties {
3.     _Color ("Main Color", Color) = (1,1,1,1)
4.     _Tex1 ("Texture1 (RGB) Gloss (A)", 2D) = "white" {}
5.     _Tex2 ("Texture2 (RGB) Gloss (A)", 2D) = "white" {}
6.     _EmissionLM ("Emission (Lightmapper)", Float) = 0
7. }
8. SubShader {
9.     Tags { "RenderType"="Opaque" }
10.     LOD 200
11.    
12. CGPROGRAM
13. #pragma surface surf Lambert
14.  
15. sampler2D _Tex1;
16. sampler2D _Tex2;
17. fixed4 _Color;
18.  
19. struct Input {
20.     float2 uv_Tex1;
21.     float2 uv_Tex2;
22. };
23.  
24. void surf (Input IN, inout SurfaceOutput o) {
25.     fixed4 tex = tex2D(_Tex1, IN.uv_Tex1);
26.     fixed4 c = tex * _Color;
27.     o.Albedo = c.rgb;
28.     o.Emission = c.rgb * UNITY_SAMPLE_1CHANNEL(_Tex2, IN.uv_Tex2);
29.    
30. }
31. ENDCG
32. }
33. FallBack "Self-Illumin/VertexLit"
34. }
35.  

 

Code (csharp):

1.        
2.  
3. Shader "Custom/IlumBlend" {
4.      
5.     Properties {
6.             _Color ("Color (RGB)", Color) = (1,1,1,1)
7.             _Texture1 ("Texture1 (RGB) Texture (A)", 2D) = "white" {}
8.             _Texture2 ("Texture2 (RGB) Texture (A)", 2D) = "white" {}
9.      }
10.         SubShader {
11.         Pass {
12.          
13.             Lighting Off
14.  
15.             SetTexture [_Texture1] {
16.             constantColor [_Color]
17.                 combine constant lerp(texture) previous
18.             }
19.              SetTexture [_Texture2]{
20.                 combine texture lerp (texture) previous
21.              }
22.         }
23.     }
24. }
25.  
26.  
27.  

Ok, this is the closest I've gotten. I don't understand or know if you can combine both textures and the colour in 1st set of {}?

 

Have you tried to write an actual shader?

 

Well I got told to look at this:

http://docs.unity3d.com/Documentation/Components/SL-SetTexture.html

So I just copied and pasted. Deleted the bits that I didn't seem to need.

Then I looked at this:

http://answers.unity3d.com/questions/377481/2-texture-blend-shader.html

When I take out the _Blend or try anything with it, I get the pink error. I don't know how to use Lerp(constant) previous or SetTexture[_] {Combine previous * primary Double} or any combination of these magic words. So I have been moving lines around to no avail.

So write, no. Amalgamate, yes.
