Directive Utilities is an open-source Unreal Engine plugin that fills gaps in the Blueprint library and editor scripting APIs. It ships as readable C++ source, and its Blueprint nodes can also be called from C++.

• Async Blueprint actions for timed updates, repeated work, asset loading, traces, and AI movement.

• Read-only editor searches and content audits for assets and Blueprints.

• Actor layout, filtering, selection, viewport, material, and mesh utilities for editor scripts.

• Progress tasks and notifications for Editor Utility Widgets.

Requirements

Supported Unreal Engine versions: 5.6, 5.7, and 5.8

Engine plugin dependencies:

• Enhanced Input, used by the runtime input utilities

• Editor Scripting Utilities, used by the editor-only utilities

Both dependencies ship with Unreal Engine and are enabled by the plugin descriptor. The plugin has no third-party libraries or external services. Source compilation requires the C++ toolchain supported by the selected Unreal Engine installation.
