Blender gives this error message whenever there is an object with no mesh data.

Code: Select all

Traceback (most recent call last):

Yes, I also experienced this some days ago. I have forgot to report this, good that it is archived here now.

This basically means that one exported object doesn't have any vertices and thus fails to generate any bounding boxes. I'll implement a better check so that these objects will be excluded from export in the future.
