.NB 3D Model Container FormatRez uses the .NB format to store it's 3D models. These work with the .PVM texture archives commonly seen in Sega games.
The .NB format in essence, is just an archive of .NJ (Ninja) files. Most of which can be extracted from Rez using the tool 'ExMldNet', though you need to rename the .NB extension to .NJ to do it.
