Release Notes

UE5 Note: For Open World games use the World Partition system built in UE5. for Linear games how ever, level streaming volumes/triggers can give more control over what levels need to be streamed. Note that World Partition can not be used with level streaming volumes or level streaming triggers.

With this plugin, you can easily and quickly set up level streaming for your games. Two lists show how each actor streams each level. Actors and levels can be grouped into colored folders for a more organized view.

It's much easier to work with Level Streaming Volumes using this plugin. there is a tool to auto-generate level streaming volumes for your levels.

Level Streaming Trigger is provided for trigger-based level streaming that works very well for buildings.

You can also extend the plugin to make it work with your custom level streaming actors just using blueprints.

There is also a box selection tool that can be used to quickly select multiple actors and move them into sub levels.
