For more elucidation on this, the omni figures do not work in P5 because P5 fixed crosstalk, and their fix did not even consider the possibility of spotlights (an omni is made from 14 of them) as body parts, nor of ERC-ing spotlights, and thus their fix killed the way they work. Use one that's already on (from an L or GL prop) and those should work. Also take note that the bullseye lantern has a transparency map done P4 style, which requires some modification to work right in P5.
