After some forum searches over at luxology it looks like lux changed the way menus are added. I fixed fs_OctaneExporter_GUI.CFG so the menu now shows up.
Get the 1.05 script here: http://www.refractivesoftware.com/forum ... =34&t=2985'
then overwrite C:\Users\USERNAME\AppData\Roaming\Luxology\Configs\fs_OctaneExporter_GUI.CFG with the new one I've attached.
This only fixes the menu... I have no idea if everything else works in 501
