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++.

Source code: GitHub repository

Requirements

Supported Unreal Engine versions: 5.6, 5.7, and 5.8

• Enhanced Input, used by the runtime input utilities

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

• zlib, supplied by Unreal Engine and used for zlib and gzip byte streams

Enhanced Input and Editor Scripting Utilities are enabled by the plugin descriptor. zlib is linked from Unreal Engine's bundled third-party libraries. The plugin has no external services or separately installed libraries. Source compilation requires the C++ toolchain supported by the selected Unreal Engine installation.

Important notes

The runtime module is available in packaged projects. Blueprint compiler, editor, and test modules are excluded from packaged games.
