Unreal Blueprint Analyzer

Read-only analysis of Blueprint binary assets in any Unreal Engine project. Treat .uasset, .umap, and similar Unreal assets as binary source files; never patch them in place.

Core rules

• Do not edit .uasset, .umap, .navmesh, or other Unreal binary assets directly.
• Separate confirmed fact from inference. Label evidence sources as source, docs, references, binary strings, or editor exports.
• Prefer the most reliable source available: official editor exports, Commandlets, user-provided screenshots, or JSON.
• If the user asks to modify a Blueprint, give safe editor steps or a scriptable editor/export pipeline, not a binary patch.

Parsing method

Prefer structured parsers over raw string grepping:

• CUE4Parse (the .NET library behind FModel) for .uasset, .umap, and .pak package structure.
• UAssetAPI for Blueprint Kismet bytecode and expression graphs.
• FModel as a ready-made viewer and exporter.
