How does this work with Level Instances

You can place actors with PRCs and PSCs however you want in persistent and instanced levels.

You can decide if the the spawned prefab is spawned in the world persistent level or in the level of the actor owning the PRC (can be the persisent level or a instanced level) with the XXX property.

Spawn in Persistent Level

Spawn in same level as the PRC Owner

Keep in mind that the default UE behavior with dynamically spawned actors is that they won't be respawned when the level is unloaded. This means that when the instanced level is reloaded the PRC will rerun whatever logic you planned, and your prefab actor will be eventually respawned.

How does this work with World Partition, Data Layers & HLOD

While no special configuration exists between Unreal Prefabs and these systems (for now), the spawned prefabs will be unloaded when no longer relevant by the World Partition system. And be fully reloaded when relevant again.

World Partition

Here the actors are assigned to a cell.

With Data Layers

Here the actors are assigned to a Data Layer.

HLOD

N/A. Didn't test with HLOD, let me know if this is important for you!
