no entry in any of the object menus.
I don't understand, the parameters in the objdef file have no entries?
Script file and physics file may not be hooked up yet, the FBX importer does need to be finished still. Just do all the configuration yourself in the .objdef in a text editor.
Unit multiplier scales the object size, so if your program happens to be exporting 100 times to small, enter 100.
I know this isn't very helpful, but the FBX importer has never crashed or not worked for me. That said, I don't touch any of the options because I set everything up correctly beforehand in the FBX file I export from Max. Looks like what you are trying to import only has a BONE_mesh or BONE_dummy in LOD0, that could be the problem there.
Upload or PM me the FBX file and resulting package if you're still having issues, and always submit the crash report with a note of what you were doing.
