How far you can go in the world?

You can go as far as you like, but, without implementing Origin Shifting you’ll start to lose precision as you get farther away from 0,0,0, as it’s a quirk of Floating Point numbers that as they get really big or really tiny they’re less able to handle small differences between values, especially tiny differences like… .0000001 or so against a value of like 100000000.
