<p dir="auto">Not sure but I think this is a bug or I at least expected something else...</p>
<p dir="auto">I made a fiddle <a href="http://jsfiddle.net/wilt/w67tzfhx/70/" rel="nofollow">here</a> to demonstrate...</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="// definition of a shape ( a 40x40 square)

<p dir="auto">The last segment seems to be missing...</p>
<p dir="auto">When I tried to import from Blender meshes from a Blender scene with multiple materials don't work correctly with ObjectLoader. ( I think is because json has't assign correctly the material to the object, it uses a single uuid. (this happens in previous versions of three.js &amp; blender exporter ( It is nothing new of this r73 version ) ).</p>
<p dir="auto">I can only use MultipleMaterial with JSONLoader ( although with the R73 I have to remove 'DbgColor' &amp; 'colorAmbient' info from .json file ) but in this case I need a json flie for every object.</p>
<p dir="auto">Here an example &gt; <a href="http://unboring.net/lab/7415/" rel="nofollow">http://unboring.net/lab/7415/</a><br>
