title: Convert DXT1 .asset to iPhone
body: <p>While building my project i get this error:</p>
  
  <blockquote>
    <p>DXT1 compressed textures are not supported when publishing to iPhone</p>
  </blockquote>
  
  <p>The file is a ".asset" used in shaders material.</p>
  
  <p>Is there any way to convert it to iPhone supported format?</p>
