Where does landscape go in world composition?

Few related questions (for a medium sized open-world game):

  • Does the landscape reside in the Persistent Level or in a sub-level (Streaming Level)?
  • Should each sub-level have its own landscape actor?
  • Are there any best practices or recommendations with regards to setting up the landscape when using a tiled heightmap for creating the level?

Hello! Just checking if anyone can help here?

Just to follow-up: we put it inside the persistent level and all seems good. We used tiled height maps and UE is able to handle the landscape streaming on its own.
