BrettMayson

BrettMayson is an independent software publisher whose open-source work revolves around streamlining the Arma 3 modding pipeline; the single title currently offered, HEMTT (Hierarchical Elitist Make Tool for Teams), functions as an opinionated build system that turns sprawling community projects into reproducible, version-controlled releases. Designed for scenario designers, texture artists, sound engineers and config writers, HEMTT automates the traditionally manual steps of PBO packing, key signing, file linting, semantic versioning and parallel addon building, while integrating natively with GitHub Actions so every commit can be validated or deployed to Steam Workshop without leaving the repository. Because the toolchain enforces consistent folder layouts, header standards and signature chains, large teams can collaborate without overwriting one another’s work, and players receive mods that load faster and crash less. Typical use cases include nightly CI builds for total conversions, rapid iteration on weapon packs, and automated packaging of terrain dependencies, all executed through a cross-platform CLI that works identically on Windows, Linux and macOS. The same rigid structure that benefits Arma 3 communities also makes HEMTT attractive to adjacent Bohemia titles that share the RV engine, so mission makers often reuse its templates for Reforger or DayZ derivatives. BrettMayson’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always installing the latest upstream release and allowing batch installation alongside other tools.
