FModel vs Reloaded-II

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.

Reloaded-II is a free, modular framework for creating mods for x86 and x64 games. Mods can be written in .NET and C#, and native mods are also supported; the project says they can use libraries and NuGet packages while running in isolation. The loader includes dependency ordering, early hooks, hot reload, real-time console and file logging, and Visual Studio debugging and profiling support. Its launcher manages multiple games and per-game mod sets, with built-in configuration, automatic updates and a mod downloader that offers one-click downloads on supported websites. The automatic installer installs Reloaded-II and runtimes in one click; the documentation says this usually takes under 30 seconds. The project says it does not modify game files and can be removed by deleting its folder. Windows users are directed to the installer, while Linux users are directed to a setup guide. Listed platforms include Windows, Linux via Wine or Proton, and macOS via Wine. The FAQ advises against using Reloaded-II with multiplayer games because games with effective anti-cheat may ban users.
