How to Make an Island or Small Map in UE5 (WorldGen Limited World)
WorldGen terrain goes on forever by default. But plenty of games need an edge: an island, a small arena, a map players can learn. This 2 minute guide shows how to turn the endless world into a limited one with the World Bounds settings, new in WorldGen 1.17.
You will see every setting on the WorldStreamingManager: Limit World Size, World Size and World Center, Rectangle or Ellipse, the Ocean and Open edges, the invisible edge walls and Load Whole World. Then a recipe for a small 1.8 km world that stays fully loaded, and four tips that save you a debugging session.
Everything is still generated from the seed and streamed on background threads. WorldGen 1.17.1 also adds heightmap terrain, built for limited worlds.
