About OpenBPX
OpenBPX is a command-line toolkit for reading and editing Unreal Engine package assets, including .uasset and .umap files. These files can contain game project data, so the toolkit is aimed at developers and technical users who need to inspect or modify packaged assets outside the usual editor workflow. It emphasizes preserving the binary structure of files while making changes, a safeguard intended to reduce accidental damage during editing. The command-line format supports use in repeatable technical workflows and scripts. OpenBPX is specifically described as a blueprint toolkit, so it relates to the package assets used in Unreal Engine projects. The available information does not identify which asset types or fields can be changed, nor does it specify compatibility with particular engine versions. Users should work on backups and confirm their target files are supported before editing. Its stated core functions are reading and safely editing Unreal package files.
