Arma 3 Tools vs Chunker

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.

Chunker converts Minecraft worlds between Java Edition and Bedrock Edition, processing worlds locally on the user's machine. It can transfer level settings and world data such as blocks, biomes, and tile entities, as well as multiple dimensions, containers, items, and in-game maps. It can upgrade or downgrade worlds between supported game versions. Inputs include world folders, ZIP archives, and MCWORLD files, with drag-and-drop support. Users can adjust conversion and export settings and save settings for later conversions. The command-line interface supports conversion and workflow integration, but requires Java 17 or higher. Entities and player inventories are not converted; structure data such as villages and strongholds is listed as unsupported or limited. Chunker is free at free and open source under the MIT license. It is available for Windows, macOS, Linux, and through a web interface. Supported versions vary by edition: the listed ranges are Bedrock 1.12.0–1.26.50 and Java 1.8.8–1.21.11 and 26.1–26.3. Check compatibility before converting a world.
