does anyone know what’s causing the mesh partition mesh terrain in 5.8 to not load?
Most likely the runtime sections are missing. You can try building your MeshPartition runtime sections manually. Also make sure you have set up the runtime transformer pipeline asset in your MeshPartitionDefinition.
I made simple level with WP + Water Plugin + Mesh Terrain with Modifiers.
And Base level with Trigger that Opens first level.
Build Mesh Partition - check;
Compiled sections in Outliner - check;
Runtime transformer pipeline ready (actually i’ve copied default one) - check
Crash on "Open Level (by Object Reference) "
or
Mesh Terrain not loading on “Load Level Instance (by Object Reference)”
Environment: Win10, UE 5.8.1 BP only Tutorial project + third person template
Is this linked? UE5.8 Mesh Partition not loading in when using level change (name or object)

Tried just released 5.8.2. New project, WP level with Mesh Terrain, level with Open trigger, build Mesh Terrain. Same crash
With “Load Level Instance” error message appear:
