So say I have a terrain that’s 1000x1000 meters with mountains and such. I want to add 100 meters on the top and right sides of the terrain making the terrain 1100x1100, but I don’t want any of the terrain already made in the 1000x1000 area to be affected.
How would I go about doing this? Would I have to export the heightmap into a raw file? If I did it that way how would I get the heightmap resolution to work correctly with it?
My desire is to be able to add onto my terrain when I wish. Does anyone have any idea how to do this?
