ChromaKey MovieTexture

[UnSpotibleShadow]

Hi!

I’m trying to make a “Holographic” video with someone in front of a green screen. i would like to get rid of the greenscreen in the video and render the person only in it.

i already did some reasearch on Chroma keying but all the options are paid…
Anyone any idea of a free option to render my Movietexture without greenscreen ingame?

Worked it out!

Using a custom shader to render the cutout from the original MovieTexture renders a “hologram” like video

Shader "MovieWithSeperateAlpha" { Properties { _MainTex ("Base (RGB)", 2D) = "white" {} _Mask ("Culling Mask", 2D) = "white" {} _Cutoff ("Cutoff", Range (0,1)) = .5 }

 SubShader 
 {
     Tags {"Queue"="Transparent"}
 
     ZWrite Off
     Blend SrcAlpha OneMinusSrcAlpha
 
     Pass 
     {    
         CGPROGRAM 
// Upgrade NOTE: excluded shader from OpenGL ES 2.0 because it does not contain a surface program or both vertex and fragment programs.
#pragma exclude_renderers gles
             #pragma fragment frag 
             #include "UnityCG.cginc"  
 
             sampler2D _MainTex; 
             sampler2D _Mask; 
 
             struct v2f 
             { 
                 float4 pos : POSITION; 
                 float4 uv : TEXCOORD0; 
             }; 
 
             half4 frag (v2f i) : COLOR 
             { 
                 half4 color = tex2D(_MainTex, i.uv.xy); 
                 half4 color2 = tex2D(_Mask, i.uv.xy); 
 
                 return half4(color.r, color.g, color.b, color2.r); 
             } 
         ENDCG         
     }    
 }
 
 Fallback "Transparent/Diffuse" 
}

The _MainTex is the full video with green/blue screen

The _Mask is a the video rendered with UltraKey/ChromaKey usage and a Alpha Output which will output a

I made a post on the forums on how to create a chroma key shader. It get’s the job done and it’s free: http://forum.unity3d.com/threads/chroma-key-in-unity-5.359119/
