Hi,
We upgraded a project from 5.2 to 5.4, and then the landscape became much higher than it should be in some open-world maps (not all the maps though). We did some investigation, found that it’s maybe the Landmass Custom Brush related, that once we toggle the Affect Heightmap from the Details Panel (not working if just toggle from the landscape UI) for the first landmass brush, it will become correct again temporarily, but once re-open the map/rebuild landscape/rebuild HLOD, it will be broken again…
Are there any known issues/solutions to the cases above? Or related ones? Or if there are workarounds e.g. we can export the heightmap and reapply again?
Thanks!

Hi Xuan,
I’m sorry but the Landmass brush is experimental and therefore not officially supported. It will remain so for the foreseeable future, as it’s not a direction we want to move the landscape tool towards.
That being said, there were several changes to the landscape tools since UE5.2 and it’s possible that the issues you are seeing are fixed. In particular, on-demand shader compilation which was still in its infancy in UE5.4 could leave to inconsistent results such as what you describe. Those issues have been fixed since. Could you try to export your landscape setup from 5.2 (or 5.4) (i.e. export the individual heightmaps/weightmaps via the import/export tool) and recreate/import it in a fresh new landscape in the latest UE version (5.7) and see if the problem can be reproduced there?
Cheers,
Jonathan
