So is there a way to copy the landscape from one level to another without having to re-import the height-map and materials again?
I managed to do it by selecting landscape directly in the editor outline, ctrl+c to copy, you get notified about it being a large memory copy, accept, open the level you’re moving the landscape to and ctrl+v to paste it in the outline. It brings over the entire landscape including materials! I was amazed it was so simple but saw this and gave it a try and it worked Can I move a landscape to another project? - #4 by Black_Phoenyx
