I just want to hash out the basic landscape of my map. How do I change the map size? It needs to be about 25km2 can I do this on one level? I know I will need enhanced tools to create the full map with all the extras but just to create the basics on one map like the mountains and the canyons so I know when making the individual levels that will later be linked up how they fit into the big picture.
I have edited the scale and this created a large map but then all the textures are also increased to a stupid size that looks odd.
