Publication boundary
Explain and cite. Do not copy.
The Unreal field manual is independently written educational guidance. It links to official sources without redistributing Epic documentation, assets, code, screenshots, or logos.
Practical conclusion
Publishing the library is reasonable within a conservative boundary.
Facts, methods, systems, and procedures can be independently described. Copyright can protect Epic’s particular prose, illustrations, screenshots, and other expression, so this project uses original wording and links readers to the official material.
This is general information rather than legal advice. A lawyer should review any future release that republishes Epic media, Engine Code, assets, or substantial documentation excerpts.
Copyright
The U.S. Copyright Office explains that copyright does not protect ideas, procedures, processes, systems, methods of operation, concepts, principles, or discoveries, although an author’s particular explanation or illustration can be protected.
Epic documentation and engine terms
The library does not copy official documentation pages or distribute Unreal Engine technology. It contains original summaries, interoperable identifiers, and direct source links. The Unreal Engine EULA continues to govern anyone’s use of the engine itself.

Trademark and independence

The contributor rule
Explain and cite; do not copy. Do not add Epic documentation prose, screenshots, artwork, logos, Engine Code, or assets unless a separate license clearly permits that exact use and the repository records it.
