We are having a display issue with tiled landscapes displaying well below full tessellation in editor, but displaying fine in game. We can "fix" this issu by unchecking "Use Default Falloff" in details tab (re-enabling it keeps the tesselation as desired, so wondering if this is a bug?). Is this a viable solution, or are there potential issues with this down the line.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-80700 in the post.
