This has been brought up before if your using the new technology lighting it isn’t live at the moment, if your lighting isn’t working when in-game it’s only studio. I would try using another lighting technology if your still wanting the spotlights to show while in-game.
There’s been a few notes coming out on the thread including “updates” and such so it’ll probably be coming sooner you should keep an eye on the thread, and see when new updates get pushed out once it’s fully releases and live to the public so it’ll be seen in games and not just studio: Future Is Bright: Phase 3 Studio Beta .
