What Arma 3 Tools is
Arma 3 Tools is a free Windows suite for creating terrains, models, addons and mods for the Real Virtuality game engine used by Arma 3. Terrain Builder is for making virtual worlds from scratch. Object Builder lets creators create, edit and configure 3D models for Arma 3. Addon Builder converts data into formats the engine can read and packages it into a single archive; it can also sign PBOs with a digital key so signed addons can be added to secure servers. Publisher sends complete mods to Steam Workshop.
The suite also includes tools for other parts of the content workflow. Game Updater aims to simplify switching between Steam branches without additional downloads each time. Tools Launcher checks some aspects of an installation, launches tools in the suite, and can detect and interact with Mikero’s tools and Poseidon Tools. Arma 3 Tools is distributed through Steam, and Publisher integrates with Steam Workshop for mod publishing. The installation manual lists a valid Steam account, an internet connection and at least 1.1 GB of free disk space as prerequisites. The suite is offered free for non-commercial use.
