If you've been working with 3D models, you may have come across NIF files, a format commonly used in game development. However, there are times when you may need to convert NIF files to OBJ format for compatibility with other 3D modeling software. Fortunately, there are several tools and methods available to help you achieve this conversion.

Here's a step-by-step guide on how to convert NIF to OBJ:

1. Use NifTools: NifTools is a set of software tools that allows for the exploration and modification of various NIF file formats. One of the tools included is NifSkope, which can be used to open NIF files and then export them as OBJ files. Simply open the NIF file in NifSkope, then go to File > Export > Wavefront OBJ to save it in OBJ format.

2. Blender: Blender is a popular open-source 3D modeling software that supports NIF and OBJ file formats. To convert a NIF file to OBJ using Blender, simply open the NIF file in Blender, make any necessary adjustments or edits, then go to File > Export > Wavefront (.obj) to save it in OBJ format.

3. Online Converters: There are also various online file conversion websites that offer NIF to OBJ conversion services. Simply upload the NIF file to the website, select OBJ as the desired output format, and then download the converted file.

4. NifTools Command Line: If you prefer using command-line tools, NifTools also provides a command-line interface that allows for batch conversion of NIF files to OBJ format. This method is useful for automating the conversion process for multiple files.

5. Nif Converter Plugin: Some 3D modeling software may have plugins or extensions available for NIF to OBJ conversion. Check if your preferred 3D modeling software has a NIF converter plugin that can simplify the conversion process.

After following any of the above methods, you should have successfully converted your NIF file to OBJ format, making it compatible with a wide range of 3D modeling and game development software.

In summary, converting NIF files to OBJ format is achievable using various tools and methods such as NifTools, Blender, online converters, command-line interfaces, and plugins. Whether you're a game developer, 3D artist, or hobbyist, having the ability to convert between different 3D file formats can greatly expand your creative capabilities.
