Free nightvision shader for unity free

Hi ,
here is a free nightvision replacement shader for the free and pro version of unity. I just converted a shader from a website. Just attach this script to the main camera, and see the effect.

Here's the script:

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class NightVision : MonoBehaviour
6. {
7.     public bool bright = true;
8.     public float brightness = 2.0f;
9.     public Shader nightvisionShader;
10.    
11.     public void OnEnable()
12.     {
13.         nightvisionShader = Shader.Find( "UnityFree/NightVision" );
14.     }
15.    
16.     public void OnPreCull()
17.     {
18.         if( bright )
19.         {
20.             Shader.SetGlobalFloat("_Brightness", brightness );
21.             Shader.SetGlobalFloat("_Bright", 1.0f );
22.         }
23.         else
24.         {
25.             Shader.SetGlobalFloat("_Bright", 0.0f );
26.         }
27.        
28.         if( nightvisionShader )
29.             transform.camera.SetReplacementShader( nightvisionShader , null );
30.     }
31. }
32.  

And here is the shader:

Code (csharp):

1.  
2. Shader "UnityFree/NightVision" {
3.     Properties {
4.         _MainTex ("Base (RGB)", 2D) = "white" {}
5.         _Brightness ("Brightness Amount", Float ) = 2.0
6.         _Bright ("Bright Areas", Float ) = 1.0
7.     }
8.     SubShader {
9.         Pass {
10.            
11.             CGPROGRAM
12.             #pragma vertex vert_img
13.             #pragma fragment frag
14.             #pragma fragmentoption ARB_precision_hint_fastest
15.             #include "UnityCG.cginc"
16.  
17.             uniform sampler2D _MainTex;
18.             uniform float _Brightness;
19.             uniform float _Bright;
20.                    
21.             half4 frag (v2f_img i) : COLOR {
22.                 half4 tex = tex2D( _MainTex, i.uv );
23.                
24.                 // greyscale the pixel color values
25.                 half4 grey = dot( half3( 0.222, 0.707, 0.071 ), tex );
26.                
27.                 if(_Bright == 1.0 ) {
28.                     // white out bright spots
29.                     if( grey.x > 0.4 )
30.                         grey *= _Brightness;
31.                 }
32.                
33.                 // boost the green channel     
34.                 grey.y *= 2.5;
35.                
36.                 return grey;        
37.             }
38.         ENDCG
39.         }
40.     }
41. }
42.  

If anybody knows why the skybox disappears , please tell me

 

Hi
Very cool shader!! Thanks a lot, but I have a problem with the Transparent Textures, witch I use in my Game. The are with this Shader no longer transparent.

Do you know a solution
