I'm making a button and when you press It the player that pressed will be the sun or their picture?
well? I mean, what do you mean? 1. a Day night cycle, this may take some time 2. Sunrays.
--sunrays --make this a local script local sunrays = game.Lighting sunrays. -- whatever, just change the properties
3.Texture
--texture --make this local script local sundecal = game.Lighting.Sky.SunTextTureid -- or whatever that property is sundecal. --change the properties
