[SOLVED] Trying to get my _Reflectiveness variable to work

Hi, I've pretty much zero knowledge on shaders, but I managed to cobble together a couple I found online.

The shader is working well until after I tried changing this:

Code (csharp):

1. o.Emission = texCUBE (_Cube, IN.worldRefl).rgb * 0.5;

to this:

Code (csharp):

1. o.Emission = texCUBE (_Cube, IN.worldRefl).rgb * _Reflectiveness;

The _Reflectiveness is always zero regardless of the amount I set on the material itself. What did I do wrong?

Full shader code below:

Code (csharp):

1. Shader "Custom/Mobile/Vertex Color Unlit Water" {
2. Properties {
3.     _SColor ("Color", Color) = (1,1,1,1)
4.     _MainTex ("Texture", 2D) = "white" {}
5.     _Cube ("Cubemap", Cube) = "" {}
6.     _Reflectiveness ("Reflection Amount", Range(0,1.0)) = 0.5
7. }
8.  
9. Category {
10.     Tags { "Queue"="Geometry" }
11.     Lighting Off
12.     BindChannels {
13.         Bind "Color", color
14.         Bind "Vertex", vertex
15.         Bind "TexCoord", texcoord
16.     }
17.  
18.     // ---- Dual texture cards
19.     SubShader {
20.         Tags { "RenderType" = "Opaque" }
21.         CGPROGRAM
22.         #pragma surface surf Lambert
23.         struct Input {
24.             float3 worldRefl;
25.         };
26.         samplerCUBE _Cube;
27.         float3 _Reflectiveness;
28.         void surf (Input IN, inout SurfaceOutput o) {
29.         o.Emission = texCUBE (_Cube, IN.worldRefl).rgb * _Reflectiveness;
30.         }
31.         ENDCG
32.      
33.         Pass {
34.             Blend One One
35.             SetTexture [_MainTex] {
36.                 matrix [_OffsetTex]
37.                 combine texture * primary
38.             }
39.             SetTexture [_MainTex] {
40.                 constantColor [_SColor]
41.                 combine previous lerp (previous) constant DOUBLE
42.             }
43.         }
44.     }
45.  
46.     // ---- Single texture cards (does not do vertex colors)
47.     SubShader {
48.         Pass {
49.             SetTexture [_MainTex] {
50.             matrix [_OffsetTex]
51.                 constantColor [_SColor]
52.                 combine texture lerp(texture) constant DOUBLE
53.             }
54.         }
55.     }
56. }
57. }

Thanks!

 

Maybe because you're trying to access it as a float3, while it is a float?

 

Not sure why I didn't spot that! Thanks, it's working fine now
