My Dynamic texture not showing up in the Build???

**I have a texture which is working fine inside unity and it is not showing up after build??**I have attached the texture code..

 **

var sides:int=5; var treshold:int=170; var texturesize=512; var alphadecayrate=.01; private var color=Color.white;

 var rep=1;
 var spread=2;
 function Start () { 
 
     //renderer.material.shader = Shader.Find ("Transnalpha");
     renderer.material.shader = Shader.Find ("Diffuse");
    shade();
 }
 
 function Update () {
     
 }
 
 function shade ()
 {
