Hi,
while trying to get a OBJ-File made in ZB into Truespace the following way worked fine for me.
When you export, make sure that you set TRI ON and also FLIP ON. Also get the free LUUV plugin for Truespace. The build in importer of TS doesn’t load the UV-Coordinates correctly. But this plug does. Get it here:

I thought that maybe someone need this info.
