Played around with RealityScan from Epic. Had a lot of fun with it.
Scanned some fresh pastry that I got from a shop earlier.
Can already use them in a scene as is, especially if it's some background stuff, like a bunch of pastry on shelves behind a character or so.
But could also spend some time, retopo them manually and reproject color and normal maps onto an optimized mesh if you want to use it for games.
