The nif file extension is associated with the Gamebryo game engine developed by Emergent Game Technologies. Gamebryo was used in games including Fallout 3, The Elder Scrolls III: Morrowind and The Elder Scrolls IV: Oblivion.
A nif file stores a game model and associated scene data, such as geometry, materials, texture references and animation information. It is part of the game's asset files rather than a general-purpose 3D model format. Gamebryo LightSpeed runs on Microsoft Windows, and NIF files are primarily encountered in older Gamebryo-based games and their development tools.
On Microsoft Windows, use NifSkope to inspect and edit compatible nif files. Gamebryo LightSpeed can also work with them as part of a Gamebryo development project.
Fallout 3, The Elder Scrolls III: Morrowind and The Elder Scrolls IV: Oblivion load their NIF assets as part of the game; they are not general-purpose viewers for opening an individual file.
NifSkope can be used to inspect or modify compatible files, but exporting a model to another 3D format may lose game-specific materials, animations or other scene information.
