Just wondering, I read posts saying 1 uu is 1cm, if I convert cm’s to km’s that is 10,000,000,000 cm for 1 km, does that mean if I want to do 500 square km’s I need to have the map size to be 5,000,000,000,000 uu? Or is uu different from the x y z value’s when you create your landscape?

Sorry I just don’t understand the measurements in Unreal Engine 4.10.4

Your conversion is off there. 1km = 100,000cm (not 10 billion :stuck_out_tongue: ). 500 square kms would be 50,000,000x50,000,000 units

And no, you wouldn’t make your map that large, you have to use World Composition to make large worlds
