Trying to create a ceiling texture/material?

OK so the game im doing starts off in a school and ive got some windows and lights for lighting but i need a ceiling that looks like a ceiling in a school and so far i cannot find anything at all. Thank you in advance.

Ummm… Try to be more specific.
Are you looking for a texture?

What’s so special about this ceiling? If it’s just a normal ceiling you could just plug in a diffuse and normal map to a material and call it done really.
