Preload Maps

Hi there.
I want to create an oldschool Action RPG.

The Maps are planned to be rather small, and I’d like to make the transition of Maps as fast as possible.

I’d like to preload the “surrounding” maps.

For example:

I’m on Map A:
Maps accessible:
Preload Maps B, C and D

Let’s say I go from Map A to Map B:
Maps accessible:
Keep Map A in Memory
Preload Maps E and Map F.
Discard Map C and Map D.

Is there a solution for this case?

Search docs for World Composition and level streaming.

I’m not using Seamless Travel or World Composition, though.
