stud texture or roblox's own studs for a retro look?

the catch with Texture is it only covers one face. for all six sides you need six of them per part. fine for a floor, painful for a whole map of bricks, so most people use a little script that loops through the parts and adds them.

built-in studs still work, set TopSurface to Studs on the part. but you get zero control over scale and it only really looks right on plastic. if you want the proper retro look across a whole map I'd use a Texture object with a stud image instead. StudsPerTileU and StudsPerTileV let you line it up with the grid exactly, and you can tint it with Color3 so one image covers every colour brick.
