World Machine Tiled Heightmap to UE5

Hi developers!
I got a tiled hightmap output with World Machine. The naming is _x%x_y%y. When importing it to UE5, I think it messes up its ordering and the hightmaps’ positions are wrong. What should be the correct naming?
How can I solve this problem?


I solved the problem and wanted to share it here. When exporting with World Machine, there is an option to reverse the y-axis. Activating it fixes the problem.
