title: Convert Texture2D to EXR (HDRI)
body: <p>I am looking for a way to convert <code>Texture2D</code> directly to EXR format in byte array. I've done few research and this seems to be complicated than I thought. </p>
  
  <p>Not really looking for a code since I don't have one. Just a suggestion on how to do this.</p>
