Arma 3 Tools vs FModel

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.

FModel is free, open-source Windows software for exploring and extracting content from games made with Unreal Engine. It can browse game archives, including encrypted ones, and compare two archive states to identify new or modified packages; encrypted archives require an AES key. It parses more than 30 asset types, displays their properties and offers image, audio and 3D viewing for supported content. Package properties can be shown in formats including JSON, INI, XML and TXT, and models can be saved as PSK files. An Export Session window supports batching raw data, model, world, texture and animation exports. The August 2026 release added USD export for meshes, animations, materials and worlds, plus WebP export and texture quality settings. Whole-level export is in USDA format, and sockets or attachments may not always be placed correctly. FModel is distributed as a portable x64 executable in a ZIP archive. It requires .NET 10.0 or later, and some games may require up to 2 GB of free RAM.
