So the land area in the base game map and terrain is not very big. As well as it isn't the most compatible as far as driving on the terrain.

My question is. Without having to install a mod, is there a way to possibly just change the scale or size values of the current islands to simply make the land masses larger and take up more of that disproportionate water volume?

Also has anyone figured out a non mod way to allow the camera to go subsurface in the water instead of being so hydro phobic.
