Extract text from Namco Universal Models (NUMDLB)
To convert NUMDLB models to another format, you need Bandai Namco Game Engine or other 3D software.
To convert other file formats to the "Proprietary Game Asset" file type, you need software like Bandai Namco Game Engine or a similar tool.
The .numdlb file extension represents a Namco Universal Model Binary, a highly proprietary 3D model container format. It is utilized extensively in video games developed by Bandai Namco, most notably within the engine running Super Smash Bros. Ultimate. The file primarily stores vertex data, mesh definitions, and the bone structures necessary to render complex 3D character models during gameplay.
Officially, these files are accessed natively only by internal Bandai Namco development tools. However, the game modding community has reverse-engineered the format, allowing users to interact with the models using specialized third-party desktop software like Switch Toolbox or SSBH Editor to open, view, and extract the assets.
The major disadvantage of the .numdlb format is its heavily proprietary, closed-binary nature. Standard 3D modeling applications cannot read or interpret its internal structures. You cannot preview these files in standard operating systems, nor are they supported by web browsers. Working with them requires a complex and heavily specialized software stack, which presents a steep learning curve and limits for casual users looking to edit or 3D print a character.
To make these models usable in standard workflows, you must convert the .numdlb file to universally supported 3D formats like FBX, DAE, or OBJ. Converting to FBX or DAE is highly recommended as it preserves the skeletal rigging data. Converting to OBJ will permanently discard all bone and rigging information, leaving only the raw, static mesh.
Because this is a closed, proprietary format heavily tied to a specific game engine, standard online converters fail to process it. Usually, only the original software or a dedicated reverse-engineering parser can properly read or export the geometric data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your NUMDLB file, detects the exact format, and lets you read the text inside.
If you want to convert NUMDLB file to , you can use Bandai Namco Game Engine or similar software from the "3D Game Model Storage" category. In the File menu, look for Save As… or Export….
To convert files to NUMDLB, try Bandai Namco Game Engine or another comparable tool in the "3D Game Model Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NUMDLB converter.
