## Requirements & limits

- Targets Win64 Unreal Engine games; compatibility is game-dependent and may require custom signatures or configuration.
- The development README targets UE 4.7–5.8, while the latest stable tag is v3.0.1 from 2024. Match documentation to the chosen build rather than assuming the stable release has every development feature.
- MIT-licensed. Current source builds require the documented C++23, Rust and CMake toolchains plus Epic-authorized Unreal submodule access; Linux cross-compilation produces Windows binaries.
