Arma 3 Tools vs UAssetGUI

Arma 3 Tools is a free Windows suite for producing content for the Real Virtuality engine used by Arma 3. Terrain Builder lets creators construct virtual worlds, while Object Builder creates, edits, and configures 3D models. Addon Builder converts source data into engine-readable formats and packages it into one archive; it can also sign PBOs with a digital key for secure servers. Publisher sends complete mods to Steam Workshop. Game Updater is intended to simplify switching between Steam branches, and Tools Launcher checks parts of an installation, runs suite tools, and can detect and interact with Mikero’s tools and Poseidon Tools. Distributed through Steam, the suite supports terrain, model, addon, mod, and script-related workflows, with PBO and FSM formats listed. Installation requires a valid Steam account, internet connection, and at least 1.1 GB of free disk space. Use is free for non-commercial work; commercial use requires Bohemia Interactive permission and acceptance of the BI Tools EULA.

UAssetGUI is a desktop tool for examining and modifying Unreal Engine game assets by hand. It supports .uasset, .umap, .usmap, .utoc and .ucas files, as well as JSON. Windows is supported directly; Linux setup runs the Windows executable through Wine. Command-line arguments can export and import UAssetAPI JSON without opening the graphical interface, and custom C# scripts can extend the program. Portable mode, available in v1.1.0 or later, keeps configuration and saved mappings in a Data folder beside the executable. The v1.1.0 release added opening and saving .utoc and .ucas containers through built-in retoc integration. Pre-built binaries and an experimental build are available from the repository’s Releases page. Release notes report support for Unreal Engine 5.6 and 5.7, while earlier notes identify limits for some Unreal Engine asset support. UAssetGUI is free under the MIT License, which provides the software without warranty. The maintainer announced retirement from UAssetGUI development, though future contributors or releases might follow.
