Hi I'm trying to expand my 500 x 500 terrain and add more blank/flat terrain around it but when I go to set resolution it just scales up/stretches my current one, and when I create a new terrain they act as 2 different terrains and don't correspond well on the edges, thanks.
Depends on how much you value your time. You could write your own, if that's cheaper than buying it. I wonder though if you could save out your heights, then change the resolution, then restore the heights. I think you could, seems like an easy script.
