Hi! So I’ve figured out how to create cliffs using the flatten tool in landscape mode—they look pretty good, except the edges of the cliffs get these jagged looking edges that really stand out. What might be the issue here, and how might I go about fixing this?
Hello Dniel109, and welcome to the Unreal community.
Congratulations on making great headway with your landscape. I agree with your initial assessment in that the edges do look a bit jagged. I found a very detailed, lengthy thread that has a multitude of solutions.
Some of the subjects are about: Smoothing the landscape, checking your FPS to ensure it is within a reasonable range, using tessellation and much more.
Here is additional reading material on Landscapes if you ever feel inclined to do more reading into the subject.
