can't import .raw/.r16 height map for landscape in ue5

2048x2048 file will be recognized as a 512x8192.
4096x4096 file will be recognized as a 2048x8192.

The result landscape is a mess.

It works for ue4.
It works if using .png file.

Did you try altering the resolution via the drop down tab? You can manually select the correct resolution when importing.
However when I do this it just plain crashes out so I’m curious to see if you have the same issues.

ue5 will crash if i manually choose the correct resolution.
