No errors loading the plugin here - got the export option of an fs2 pof.
I do get an error re: missing DLL files (ViewportManager.gup) when trying to load the sample scene, natch. It's presumably a version difference (I'm assuming the max file is v5, so theres some change there?), but it means I'll have to setup and test my own scene to see if this works on my machine.
EDIT; ok...tried converting a single lod mesh (mesh & 1 subobject), and, er max crashed (just 'an error has occured' type message, no other info). Could this just be leaving the debris, etc, checkboxes unticked?
Also, i'm now getting this error on startup, and don't have the pof export option....
Think it's just that it's not been dereferenced by max, not sure.
EDIT2: same as omni, I notice.
EDIT3: doesn't export with options turned off, either. I'm going to check if it I can get a single object out, maybe just linked the damn thing wrong. (EDIT: nope).
I just checked, though. I have max 4.0, not 4.2 Bugger.
