I would need to get a copy of the scene (jeremy at nextlimit dotcom, or use dropbox if it is too large for email) before I could tell you much about this. The only case in which this error message is given is when the object being exported either has an invalid (returns null) points array, or has an array which contains zero points. The reason for that could be anything, since polygons are provided by Cinema or other plugins.

In the process of stripping the scene file I seem to have discovered the issue.

If I include frame 0 (where there is no mesh) then my export to maxwell returns the error. If I exclude frame 0 from the sequence it exports ok.

Cheers!
