RGB Split Shader

I'm nit a shader programmer, but would appreciate if someone can point in the right direction. I want a shader that does an RGB Split like in the video posted below.

I wouldn't mind to buy it off the asset store but I checked most of the packages and none seem to have it.

 

My "aubergines postprocess effects" pack has this effect. Its the _Lightwave shader in the package.
You need unity pro for it.

 

excellent .. buying now

 

I have my email in the readme file, let me know when you need customization or extra features as its pretty generic out of the box.

 

Thank for the quick response. Got my customized shader in minutes.

This is the link to the asset on the store

 

For those who want to know the basis for how its done, heres a free example below

Reference : http://blog.jahfer.com/2012/04/02/experimenting-shaders-openframeworks/

Code (csharp):

1. Shader "Custom/ChromaticAberration" {
2.     Properties {
3.         _MainTex ("Base (RGB)", 2D) = "white" {}
4.     }
5.     SubShader
6.     {
7.         Pass
8.         {
9.        
10.         CGPROGRAM
11.         #pragma vertex vert_img
12.         #pragma fragment frag
13.         #pragma fragmentoption ARB_precision_hint_fastest
14.         #include "UnityCG.cginc"
15.  
16.         uniform sampler2D _MainTex;
17.         uniform float _AberrationOffset;
18.  
19.         float4 frag(v2f_img i) : COLOR
20.         {
21.  
22.             float2 coords = i.uv.xy;
23.            
24.             _AberrationOffset /= 300.0f;
25.            
26.             //Red Channel
27.             float4 red = tex2D(_MainTex , coords.xy - _AberrationOffset);
28.             //Green Channel
29.             float4 green = tex2D(_MainTex, coords.xy );
30.             //Blue Channel
31.             float4 blue = tex2D(_MainTex, coords.xy + _AberrationOffset);
32.            
33.             float4 finalColor = float4(red.r, green.g, blue.b, 1.0f);
34.             return finalColor;
35.        
36.         }
37.  
38.         ENDCG
39.         }
40.     }
41. }

C# code, gets attached to the camera

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. [ExecuteInEditMode]
5. public class ChromaticAberration : MonoBehaviour {
6.    
7.     #region Variables
8.     public Shader curShader;
9.     public float ChromaticAbberation = 1.0f;
10.     private Material curMaterial;
11.     #endregion
12.    
13.     #region Properties
14.     Material material
15.     {
16.         get
17.         {
18.             if(curMaterial == null)
19.             {
20.                 curMaterial = new Material(curShader);
21.                 curMaterial.hideFlags = HideFlags.HideAndDontSave; 
22.             }
23.             return curMaterial;
24.         }
25.     }
26.     #endregion
27.     // Use this for initialization
28.     void Start ()
29.     {
30.         if(!SystemInfo.supportsImageEffects)
31.         {
32.             enabled = false;
33.             return;
34.         }
35.     }
36.    
37.     void OnRenderImage (RenderTexture sourceTexture, RenderTexture destTexture)
38.     {
39.         if(curShader != null)
40.         {
41.             material.SetFloat("_AberrationOffset", ChromaticAbberation);
42.             Graphics.Blit(sourceTexture, destTexture, material);
43.         }
44.         else
45.         {
46.             Graphics.Blit(sourceTexture, destTexture); 
47.         }
48.        
49.        
50.     }
51.    
52.     // Update is called once per frame
53.     void Update ()
54.     {
55.        
56.     }
57.    
58.     void OnDisable ()
59.     {
60.         if(curMaterial)
61.         {
62.             DestroyImmediate(curMaterial); 
63.         }
64.        
65.     }
66.    
67.    
68. }

 

This looks quite awesome! I was wondering if there was a possible solution for Unity Free to achieve something similar to the referenced post: http://blog.jahfer.com/2012/04/02/experimenting-shaders-openframeworks/? Cheers~

 

You are better of using Echologin's Post FX here: https://www.assetstore.unity3d.com/#/content/13919
You can do that effect and so much more.

 

Thanks for the heads up! Much appreciated.
