Eitherway for that kind of ceiling I recommend making it ripped, with metal plates, and cables coming out of it. Usually in ceilings there are electrical cables so you could also add those, you can even make some look “ripped”
You could also add dirt/blood splatters if the game genre allows it
Realism in roblox is just a combination of good lighting, good use of pbr textures, good use of models, there ain’t really that much else you can do in vanilla studio.
