If you are still interested, there are model tools made by a user named "cra0kalo" You can import .fmdl files and export them as .smd (source engine raw format, comes with bones) or .obj (no bones) The tools were never finished, so the import function to conver TO .fmdl is not working but the import/export OF .fmdl does work http://dev.cra0kalo.com/?p=268
