I tried exporting in XSI using the dotxsi exporter, all variations (3.0-3.6 and text/binary) as well as trying to use crosswalk? to export XSI 5-6 binary/text none of these seem to be accepted by the mesh converter tool provided in the beta tools. I have gotten shps in with both code herders tool and the Max exporter, but they both have some issues. I'm curious if anyone has figured out the right export format for the XSI?
