5 days of struggle... importing a Heightmap

So I am having big issues with importing my heightmap of the Arizona dessert.

it is pretty big and when importing UE seems to crash.

if I scale it down its very small and the ground get small spikes everywhere.


Didn’t have any issues importing that to Unity. but then there is tons of other issues with that engine that’ s why we chosen UE4.

Is there any work arounds on this ?

That is a crazy huge landscape. Resize your heightmap to 8129x8129 and try to import again.

Arizona desert huh? Try scaling it down a LOT, you can smooth out everything later
