HLOD proxy generation invalidates other clusters

HLOD proxy generation invalidates other clusters

UDN
Description

When rebuilding a single HLOD proxy mesh in a world composition level that has many, the other proxy meshes will be marked as unbuilt and removed from the HLOD asset package.

 

Steps to Reproduce
  • Open test project
  • Open /Game/Developers/lmainguy/HLODBug/World
  • Open the world composition tab & double click on the Sublevel0 to load that level
  • Open the HLOD Outliner
  • Click rebuild all
  • At this point, all LODActor should be built
  • Select one of the cube
  • In the Details panel, check the "Overriden Light Map Res" property and change the value to 128
  • At this point, the LODActor associated with this cube should be "Unbuilt"
  • Right click on the "Unbuild" LODActor in the HLOD Outliner and select "Rebuild Proxy Mesh"

Result: The other LODActors are now "Unbuilt"

Expected: All LODActors should be built
