FModel vs xEdit

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.

xEdit is a free Windows utility for editing Bethesda game plugins and resolving potential mod conflicts. Its documentation covers Enderal, Oblivion, Skyrim, Fallout 3, Fallout: New Vegas, Fallout 4, Fallout 76 and Starfield modes. The tool can remove extraneous or duplicated references, repair deleted references, merge plugins and check for mismatches between module files and xEdit record definitions. Quick Auto Clean automates cleaning while saving intermediate steps, and users can review its changes afterward. Cleaning workflows can be configured with Mod Organizer 2, Vortex and Wrye Bash, and can produce a LOOT report. Supported formats include TES3, TES4, FO3, FNV, TES5, SSE, FO4, FO76, SF1, BSA and BA2. Documentation is provided in the Tome of xEdit. Builds are distributed through Discord, while feature requests and bug reports go to GitHub. The license is MPL-2.0.
