Blender vs sizes

Greetings good people :slight_smile:
Yep, it’s weekend, I cant help it :slight_smile:
Okay, I know more or less how to make a landscape in Blender, and how to UV texture it, and the result looks promising, even though more XP is called for :slight_smile:
How would I go about making a landscape that in itself existed out of little qsuares that seamlessly match up?
Any tips?
