Bug in LuxBlend - degenerate normals

[tomb]

Hi,

I tracked down some strange artifacts in my test scene to LuxBlend exporting [0 0 0] normals. I've attached a small .blend that demonstrates the issue.
Could someone familiar with bpython have a look and see if they can spot the error in the code? It exports ok in for example openinventor format.

This is with the CVS version btw

I tried out your .blend and indeed there were many zero length normals. It seems however that Blender itself is giving these normals and in the case of this .blend, I exported in openinventor format and the [0 0 0] normals were still there.

The cause of these normals are some doubled vertices on the center of the object. I got rid of them by using the Rem Doubles button and then all normals were fine.

Does this solve your problems on your original test scene?
