Unreal engine 5.7.1 Map generation Bug?

Hello fellow dev’s, I have a question; When I try to load a heightmap as world map in unreal engine 5.7.1 it keeps only rendering 1 corner of the heightmap and repeating it as a tile rather then loading the full heightmap.

I tested the same heightmap on engine 5.4 and it worked fine, backloading and then updating the file to 5.7 destroys that map for some reason.

the dimensions I am working with are 4096x4096

I am trying to implement a 10x10KM map with 3K height, Are my calculations incorrect?
I use 10000x100/4096 for the X/Y axis and 3000x100/512
These same calculations worked fine in older engines so i’m not sure if this is the problem or if it is a bug with unreal engine 5.7.1

Any advice?

While not a longterm solution as it’s not a fix to this problem;
What ended up working for me was starting a project in engine 5.4, implementing the map in that version with the same calculations; Loading the landscape partitions, doing a bit of work like setting up a landscape material on the landscape; painting a bit; setting up some scene lighting and whatnot; the usual stuff you do early on.
And then opened up engine 5.7, loaded the project up on that version as a new copy of the project.
So far, that has been the only way for me to get the full 10x10km map to load normally on 5.7.
Hope it works for you too until a better solution comes along!
