NBA2KX Mod Tool (2K12 Supported) - Support Thread - Tutorial
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.
NBA 2K12 3DM Mod Tool - Support Thread - In Chinese
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.
Court Logos Normalizer (for non-US residents) - Support Thread
This tool attempts to fix the "licensing issue" with inaccurate and unfixable court logos for non-US players. Your mileage may vary since the tool requires that you have the US version of the game executable which is not allowed to be distributed on these forums.
NBA 2K12 Cyberface Textures Exporter/Importer - Support Thread - Tutorial
A simple alternative to using the Mod Tool. The Cyber Face Texture Importer/Exporter will automatically extract all of the textures contained in a player's IFF file (png####.iff) allowing for easy access to all the textures at once. Textures are exported as dds files and need to maintain proper formatting and size requirements to use this tool.
NBA 2K12 Cyberfaces Manager - Support Thread
This fantastic little tool allows us to edit the players within a roster. Specifically, it lets us apply Cyberfaces to Created Players, change skin tone, eye color, and change the Cyber Face ID for all players. Very useful for those creating Total Conversion mods.
NBA 2K12 Jersey Textures Importer/Exporter - Support Thread - Tutorial
Very similar to the Cyber Face Texture Importer/Exporter, this tool exports the basic uniform textures for editing into DDS files. Those DDS files do require proper formatting and size requirements to properly import.
Keep My Mod - Support Thread
Very useful tool that allows users to keep their modified files, even though 2K Sports official updates the same file. While being able to officially update inaccurate courts, uniforms, and faces is great for console users, with all the community patches we make for the PC, it can be very annoying when these updates cannot be used.
NBA 2K12 My Player Cyberface - Support Thread
Great tool for My Player users. This allows you to open your My Player save file and apply a Cyberface to your player. Very useful if you want to have a custom Cyberface of yourself but don't want to use the Creating a Legend mode. This tool also allows you to change skin tone, which is very useful if you pick the wrong one at the beginning of your career.
Miracle My Jersey/Stadium - Support Thread
This tool allows you to edit the shading and lighting effects on each individual uniform iff file. What previously took hours for a certain administrator, can now be applied to all uniforms in NBA 2K12 in minutes.
