Features & Information
Remove shadows, fog, makes the ambient a good color, makes the brightness 1, and makes the time of day 12:00pm. It also saves changes to those properties for when you turn it off
When you execute the script, just execute it again to toggle the fullbright
I mean you can kinda search the old fullbright script such as this > https://scriptblox.com/script/Universal-Script-fullbright-1324
