World Partition & Levels

Blueprint AI configures the open-world side of a project: World Partition streaming and runtime grids, Data Layers, per-level World Settings and GameMode overrides, and the editor’s Levels-window state.

Note

World Partition and Levels ops act on the editor’s open world — ask the AI to open the map first. Each op returns an actionable diagnostic if the right level isn’t loaded.

World Partition runtime

Open the map LV_Arena and enable World Partition streaming Set the MainPartition runtime grid’s cell size to 25600 and loading range to 51200 on LV_Arena Show the World Partition settings for LV_Arena

Data Layers

Create a runtime Data Layer called Foliage and an editor Data Layer called Blocking on LV_Arena Add the selected actors to the Foliage data layer Toggle the Blocking layer’s editor visibility and list the data layers

Per-level World Settings

Set the GameMode override on the LV_Manor persistent level to BPGM_Horror Read the World Settings for the LV_Manor_Combat sublevel

Levels window

Add LV_Manor_Props as a streaming sublevel of LV_Manor and make it the current level Lock LV_Manor_Lighting and mark it as a lighting scenario Set LV_Manor_Props visible

Tip

Streaming method, level color and transform, and per-level runtime flags are all configurable — and list_streaming_levels surfaces each sublevel’s full state for the AI to read before changing anything.
