title: Unity 2019.1.0f2: Blender could not convert the .blend file to FBX file
body: <p>I didn't touch anything but:</p>
  
  <ul>
  <li>launch Unity Hub</li>
  <li>clicked on "Official Releases"</li>
  <li>choose Unity 2019.1.0f2</li>
  <li>installed it</li>
  <li>opened my projects</li>
  </ul>
  
  <p>When the (very long) import is done, I get this error :</p>
  
  <pre><code>Blender could not convert the .blend file to FBX file.
  You need to use Blender 2.45-2.49 or 2.58 and later versions for direct Blender import to work.
  </code></pre>
  
  <p>Of course, I'm using the latest version of Blender (<code>2.79b</code>) and everything was working flawlessly with Unity <code>2018.3.13f</code>.</p>
  
  <p>So none of my projects work because of this problem. If I re-open it in previous Unity version (<code>2018.3.13f</code>) <strong><em>it works</em></strong>.</p>
  
  <p>Everything I've found so far on Internet is about "Microsoft released something that made Python work differently hence this problem". But this can't be that problem right now.</p>
  
  <p>Any idea?</p>
