Engine crashes when trying to import large tiled heightmap in 5.3

Hi Demenzun.

Really appreciate all of your UE related videos. Particularily the ones related to world partition.

Since trying out UE5.3 today. I have finally been able to import 8k heightmaps. Previous versions would crash at anything at 4k or higher. Not sure why. I figure this new batch import process is doing its thing.

What I am wondering is if it is still a worth using tiled maps at all? I know it does work. I just wondered if it would allow for larger imports when using multiple tiled heightmaps?

In UE4.27 I am able to import an absolutely huge map which is made up of 1k tiles, scaled to 200% X&Y. The world I was creating was 80x80km roughly. But in UE5 i have just not been able to do so.
