  <description><![CDATA[Hi,<br />
<br />
I just upload a spaceship I made:<br />
<a href="http://www.shapeways.com/model/95650/proctor_spaceship.html" target="_blank">http://www.shapeways.com/model/95650/proctor_spaceship.html</a><br />
However the side that was mirrored appears to be transparent in the render of shapeways ? Is the model ok, or should I worried ? When I open the submitted .stl file in Cinema4d, everything is fine...so I am wondering if it's not the render engine of the site ?]]></description>

  <description><![CDATA[If you mirror an object, in some apps this leads to the normals flipping (normal direction defined by vertex/edge order)<br />
<br />
Looks like that is what happened here.<br />
After you mirror the object, see if you can &quot;flip the normals&quot; back.<br />
<br />
Not sure what will happen with printing though, usually singular inverted volumes are fixed, but it might lead to unwanted subtractions when volumes overlap.<br />
<br />
As for the preview render, that is always very creative with how to display meshed <img src="http://www.shapeways.com/forum/images/smiley_icons/icon_wink.gif" border=0 alt="Wink"><br />

  <description><![CDATA[Ok. I will check this out then. I though the normals were already fix...but I will take a look back.<br />
<br />
Yah. The normal are inverted. I think I will take the time to add more details and make a stand too.]]></description>
