I've been brainstorming and coming up with and idea for an open world fantasy rpg. Only problem is I'm wanting a much larger editable map size compared to the max that it let's us edit. I also want to see if there is a way to get trees and vegetation to spawn outside of the editable area. Mainly due to it just looking strange when your on a mountain top and see baren land with the trees getting cut off in a straight line. Btw I don't know how to code, but I'm willing to start learning because I believe in the product. Any answers or information is much appreciated. Thank you.

Unfortunately neither of those are possible at the moment.
Perhaps this may be improved as development continues but there currently isnt really a lot you can do to increase the map size

@synchromesh I'm looking forward to future development then.
