What is a NUMDLB file?
A NUMDLB file is a 3D model used by a Bandai Namco video game, such as Super Smash Bros. Ultimate. It contains binary data used to show a character or object in-game. NUMDLB files are most commonly used to mod Super Smash Bros. Ultimate characters' appearances.
Most Super Smash Bros. Ultimate players will never encounter a NUMDLB file. However, some modders extract and edit NUMDLB files to alter characters' in-game appearances. While other Bandai Namco video games use NUMDLB files to store 3D models, those games' players do not typically extract and edit NUMDLB files. So, if you have encountered an NUMDLB file, it likely originated from Super Smash Bros. Ultimate.
How to open a NUMDLB file
Super Smash Bros. Ultimate modders can open NUMDLB files in Blender (cross-platform) with the io_scene_numdlb add-on installed. Modders can also open NUMDLB files and convert them to and from other 3D model formats, such as .DAE and .FBX, with StudioSB (Windows).
