This makes it possible to have worlds broken up into smaller chunks so that only the relevant parts of the world are taking up resources and being rendered at any point. text/html 2022-12-15T14:11:54+00:00 Anonymous (anonymous@undisclosed.example.com) https://docs.unamedia.com/ue5-multiworld/comparison-to-pocketworlds?rev=1671109914&do=diff MultiWorld vs PocketWorlds The following is a brief comparison following a very quick analysis of the PocketWorlds plugin shipped with the Lyra sample, so it could be not accurate.
