It’s the lightning module by Quasiduck
I have copied all the scripts directly into my game but the lightning effects only show up when I press “run” not “play.” I believe it’s because all the effects are server sided but when I put it into a local script it doesn’t show up even in the “run” mode. I read a few comments and it seems I need to do what BuildThomas said, “You can set up the module on the client and then have the server broadcast wherever effects need to happen, then pick that event up client-side and invoke the module with that.” Any idea how I achieve this though?
