I didn't have a problem with the obj exporter, maybe you're in the wrong coordinate system? IIRC you need to flip one of the axis going from ES to 3DGS. I'm really curious about the dll though, weird I'll try to get a real basic dll up and see if it shows up, if it does then I can put some debug code in the hmp exporter and see hat is going on on ur guys' machines.

P.S. Ping Locoweed and ask him which axis(es)(sp) need to be swapped when importing ES obj files into MED.
