Here is a sectored grid map you can use to determine what maps to where. I got it from the Big Kahuna winners, Tim Coleman and O.D. Wolfson, who made "Bowlin' fer Souls." I don't remember the name of their studio. BTW, It looks like 3D Expo and the Big Kahuna content are now defunct, along with 3D Magazine. The web version, 3D Gate, is still active. SMcQ
