Arma 3 Tools
What it is
Arma 3 Tools is a free Windows suite for creating content for the Real Virtuality game engine used by Arma 3. Terrain Builder lets users build virtual worlds, while Object Builder is for creating, editing, and configuring 3D models. Addon Builder converts data into engine-readable formats and packages it into an archive; it can also sign PBOs with a digital key for secure servers. Publisher publishes complete mods to Steam Workshop. The suite also includes Game Updater, which aims to simplify switching between Steam branches, and Tools Launcher, which checks some installation aspects and runs tools. The launcher can detect and interact with Mikero's tools and Poseidon Tools. The suite is distributed through Steam and is intended for making Arma 3 terrains, models, addons, and mods. Installation prerequisites listed in the manual include a valid Steam account, an internet connection, and at least 1.1 GB of free disk space. Use is free for non-commercial purposes; commercial use requires Bohemia Interactive's permission, and users must accept the BI Tools EULA.
