Hi! Ok I don’t know if this is a true bug or if that what I’m trying to achieve is just not possible.
I have created a very large 32x32km landscape (24500 actors) with world partition streaming enabled. Virtual texture support is also enabled.

When I try to build the World Partition Editor Minimap the process runs for ~3.5 minutes and then stops, it doesn’t regenerate the Minimap.

So I tried the command line route:

UnrealEditor My_Project.uproject My_Map.umap -run=WorldPartitionBuilderCommandlet -AllowCommandletRendering -builder=WorldPartitionMiniMapBuilder

After the command runs for a few seconds I get following error message:

[2024.03.24-18.14.44:739][ 14]LogWorldPartitionBuilder: Verbose: Loading Bounds: Min X=1228800.000 Y=-204800.000 Z=-11446.143, Max X=1331200.000 Y=-102400.000 Z=211009.112

Does this mean I don’t have enough memory, or is something wrong with my map/something within the engine? Does this command try to load all StreamingProxies at once? (I know that this doesn’t work with my hardware) The funny thing is, initially, when I finished importing the heightmaps and added a material to the whole map I actually was able to generate a Minimap from within UnrealEditor. Is there something I have to change/reduce to generate a Minimap from such a big landscape?

Best regards,

Ok I found out how I can get this to work again myself. But first:

For the love of the mental health of everyone building levels for computer games…
please please please add this to the tutorial. I found the solution in a buried thread that was over a year old.

In UE5.3 you have to add a “World Partition Mini Map Volume” under: Add to the Project->Volumes
Then drag this volume to the center or enter the coordinates manually and scale it up until it is as big as your map.

Please again, I searched for over a week for this little detail, add this to the Tutorial.

Awesome, sir! I truly appreciate it. I spent two days racking my brain until I found your info,
