Importing heightmaps from Gaea to 5.4 beta askquiff for everyone or am I just lucky?

So… playing around with the new 5.4 and I can’t seem to get past heightmap importing. I end up with a massive wall around part of my map:

Additionally, anyone else get this error with 5.3+ when activating the water plugin and if so, how can I resolve it?

In Gaea check your build resolution. Unreal engine has specific map size settings. click on it and it should show you the unreal size to pick. eg: 2049 is 2017 for exporting to Unreal.

Cheers. I know I have to use a 1023 resolution as that is the max I can work with in the free Gaea. Then I use the typical math (X/Y = Map Size x 100 / resolution, Z = Max Height x 100 / 512).

I’ll take another look and see if I got it wrong.
