What Arma 3 Tools is
Arma 3 Tools is a Windows suite for creating content for the Real Virtuality engine used by Arma 3. Terrain Builder lets creators make virtual worlds, while Object Builder is for creating, editing, and configuring 3D models. Addon Builder converts data into formats the engine can read and packages it into an archive; it can also sign PBOs with a digital key for use on secure servers. Publisher sends complete mods to Steam Workshop. Other utilities help switch between Steam branches, check parts of an installation, and launch suite tools. Tools Launcher can also detect and interact with Mikero’s tools and Poseidon Tools. The suite is distributed through Steam. Installation prerequisites include a valid Steam account, an internet connection, and at least 1.1 GB of free disk space. Arma 3 Tools is free for non-commercial use, but commercial use requires Bohemia Interactive’s permission, and users must accept the BI Tools EULA.
