NBA2KX Mod Tool (2K12 Supported) - SUPPORT THREAD - TUTORIAL
Not yet compatible with 2K13 CFs and Jerseys
The oldest and most updated IFF editing tool there is. Supports both textures (dds only), and 3D models (Tutorial). Supports almost every IFF file in the game, cannot handle uniform names or numbers.
3DM Mod Tool - SUPPORT THREAD
A new tool that does the same thing as the other Mod Tool, but also supports Uniform Numbers. A bit more complicated to use since it is completely in Chinese and requires users to right click each texture or model to import/export. Also requires the user to "save" the IFF file for changes to be applied. This tool does support more 3D models such as the scorebug than the above Mod Tool.
