Tried to find posts about this, none found from the last year.
Edit:
Even more concerningly my old experiences work in-studio and in-game, but once I go into one of them and publish without touching a thing it becomes bugged as well to not work in client.
PSA: This happens to my friend as well who is testing with me…
Do you mean Lighting.LightingStyle? That’s still in Studio Beta, try disabling “Unified Lighting” in your Studio Beta Features menu and checking what Lighting.Technology is when you re-open the place after restarting Studio.
