* Collection entry holds the Transform, Bounds and Index to the shared configuration. This removes the dependency on components being loaded to create runtime data for partitioned worlds. * Removed commented references to SparseClassData since that approach won't be used (actor component not supported) * Runtime data now points to a shared configuration from the collection instead of holding a copy * Subsystem tracks components registered at runtime so the collection can be updated accordingly since those entries won't persist outside of loading range * Moved most initialization code for the subsystem to the OnWorldComponentsUpdated callback since active level collection is set and actors from the persistent level registered. [WorldPartitionBuilder] * Added OnPartitionBuildStarted/OnPartitionBuildCompleted virtual methods * New UWorldPartitionSmartObjectCollectionBuilder to build SmartObjectCollection in partitioned worlds #preflight 61814a46fc786a0001447995 #jira UE-105113 #rb maxime.mercier #ROBOMERGE-AUTHOR: yoan.stamant #ROBOMERGE-COMMAND: FnMain #ROBOMERGE-SOURCE: CL 18019580 in //UE5/Main/... #ROBOMERGE-BOT: STARSHIP (Main -> Release-Engine-Test) (v885-17909292) #ROBOMERGE[STARSHIP]: UE5-Release-Engine-Staging Release-5.0 #ROBOMERGE[bot1]: Main [CL 18019655 by yoan stamant in ue5-release-engine-test branch]
