JUEParse 0.1.0-alpha.2 is an independent Kotlin/JVM implementation for read-only inspection of Unreal Engine cooked data. Production parsing runs without a .NET runtime, C# sidecar, external parser process, or production dependency on CUE4Parse.

Highlights

  • Pak, IoStore, UE5 Zen Package, USMAP, and Generic UObject parsing remain available through the Kotlin/Java API and CLI.
  • The repository layout is simpler: public modules live under modules/, development and verification tools live under tooling/, and community documents live under .github/.
  • A natural Japanese guide is now available in README_ja.md.
  • Public package names, Gradle project names, Maven coordinates, and parser behavior are intentionally unchanged.

Fortnite 41.20 validation

The current compatibility evidence is the existing deterministic 50-package local corpus measured with caller-supplied inputs: 50 packages parsed, 0 package failures, 598 exports discovered, 566 Generic UObjects decoded, and 32 bounded raw exports. Alpha.2 contains no intentional parser behavior changes and does not relabel that result as a new real-data measurement.

No game files, AES keys, mappings, Oodle binaries, private paths, or proprietary decoded values are included in this release.

Known limitations

Pak and IoStore version coverage is incomplete. Schema-index, native-serializer, and bulk texture/audio/mesh gaps remain, and the measured differential corpus still contains partial objects. VALORANT compatibility is not currently measured. See docs/compatibility.md for the evidence and exact limits.

Downloads and checksums

Download the required asset and SHA256SUMS, then compare its SHA-256 digest with the matching line. For example:

sha256sum -c SHA256SUMS

On PowerShell, use Get-FileHash -Algorithm SHA256 <file> and compare the lowercase digest with SHA256SUMS.

The Maven coordinates are prepared, but version 0.1.0-alpha.2 is not published to Maven Central. The attached JARs and CLI archives are the release deliverables.
