Hi Peter, unfortunately I don't know if there is anything I can really do about it - Vue crashing makes it pretty likely that this is due to a bug in their OBJ reading code.

A lot of other modeling systems only export triangles to OBJ files, so they probably have tested most frequently only with that type of polygon structure.

Some bugs that involve overwriting memory can be kind of sporadic, it is possible due to luck sometimes that the bug might not be triggered on certain machines. That's probably what is happening here.

My best advice is to try and send them several different examples files, it also helps for debugging if the files are kind of small and as simple as possible.

Until then you'll have to use just the triangle option to get your data into Vue 6.

Let me know if they say that there is any problem with the OBJ file itself...
