Hi, this seems like a great addon, but there is no P3D option in my File->Import/Export menus.
I have placed the files (io_export_ofp_p3d.py, io_import_ofp_p3d.py and the folder ofp containing __init__.py, mlod.py and resolutions.py) in Blender Foundation\Blender\2.66\scripts\addons.
I did notice that my __init__.py folder is empty, is that a problem? Any ideas?
