Organize complex levels, prevent accidental edits and take direct control of Unreal Engine’s World Outliner.

Outliner Tools is an Editor-only Code Plugin that extends the World Outliner with actor locking, selection protection, custom folder colors and persistent actor Collections.

Designed for both Blueprint and C++ projects, it provides a faster and clearer workflow without adding runtime systems or dependencies to your packaged game.

Lock Actor Transforms

• Lock or unlock individual actor transforms directly from the World Outliner.

• Prevent accidental movement, rotation or scaling.

• Apply Lock recursively to complete folders and nested subfolders.

• Actors added to a controlled folder inherit its effective folder rule.

Control Actor Selection

• Make individual actors selectable or protected from editor selection.

• Apply selection rules recursively to complete folder hierarchies.

• Protected actors are removed from the current selection and cannot be selected accidentally.

• Targetable only affects editor selection. It does not modify runtime collision, traces, input or gameplay targeting.

Custom Folder Colors

Assign custom colors directly to World Outliner folders and create a clearer visual hierarchy for large levels.

• Custom open and closed folder icons.

• Persistent per-map colors.

• Dedicated Reset Folder Color action.

Outliner Collections

Create logical, color-coded actor groups without modifying the existing folder hierarchy.

• Create Collections with custom names and colors.

• Assign multiple selected actors at once.

• Allow one actor to belong to multiple Collections.

• Display compact colored markers for Collection membership.

• Apply subtle full-row highlighting based on Collection priority.

• Rename, recolor, reorder and delete Collections from a dedicated manager.

• Search for actors using their Collection names.

• Select every actor assigned to a Collection from the Collections column header.

Persistent Map-Aware Organization

Outliner Tools preserves its organization data when saving, closing or reopening the project.

Persistence has been validated across:

• Normal Save and First Save.

• Save As.

• Map duplication and copying.

• Map renaming and moving.

• Folder renaming, moving and deletion.

• Editor restart.
