BNFM File – What is .bnfm file and how to open it?

BNFM File Format

A BNFM file is a Wii U 3D model format developed by Nintendo. It stores the geometry, textures, and animation data for 3D models used in Wii U games. BNFM files are typically packed in a BNVL archive, which also contains other resources such as sound effects and music.

BNFM files are a proprietary format and are not directly editable by end-users. However, there are a number of tools available that can be used to extract and view the contents of BNFM files. These tools can be used to create custom 3D models for Wii U games or to modify existing models.

Using Software

BNFM files, containing 3D models for the Nintendo Wii U, require specialized software to be opened and edited. One popular option is Blender, an open-source 3D modeling and animation software. To open a BNFM file in Blender, follow these steps:

1. Install the BNFM Import/Export addon from the Blender Market.
2. Open Blender and go to the “File” menu.
3. Select “Import” and navigate to the BNFM file you want to open.
4. Blender will import the model, preserving its textures, materials, and animations.

Another useful tool for opening BNFM files is Nus3bank, a command-line utility developed by the Nintendo Homebrew community. It allows users to extract and convert BNFM files into various formats, including OBJ, FBX, and 3DS. To use Nus3bank, open a command prompt and navigate to the directory where the BNFM file is located. Then, enter the following command:


nus3bank extract -i input.bnfm -o output.obj


This command will extract the 3D model from the BNFM file and save it as an OBJ file, which can be opened in most 3D modeling software.

Additional Notes

It’s important to note that BNFM files are highly optimized for the Wii U hardware and may not be fully compatible with other platforms. Additionally, opening and editing BNFM files may require advanced knowledge of 3D modeling and animation techniques.

File Format:

BNFM files are proprietary 3D model container formats used by Nintendo’s Wii U console. They store a combination of geometry, texture, and animation data, which are typically extracted from the internal file systems of Wii U games. BNFM files are encoded in a binary format that can be difficult to interpret without specialized tools or software.

Usage:

BNFM files play a crucial role in rendering 3D models within Wii U games. The geometry data within the files defines the shape and structure of the models, while the texture data provides visual details such as colors, materials, and patterns. The animation data allows the models to move and deform in a realistic manner, creating dynamic visuals and gameplay experiences. BNFM files are essential for developers to create and implement detailed and immersive 3D environments in their Wii U games.

Tools and Extraction:

Due to their proprietary nature, BNFM files are not compatible with standard 3D modeling software or viewers. Specialized tools have been developed by enthusiasts and modders to extract and convert BNFM files into more accessible formats such as FBX or OBJ. This allows 3D artists and hobbyists to view, edit, and manipulate Wii U game models for various purposes, including fan art, model viewing, and game modifications.
