To make NBA 2K25 motions work in NBA 2K23, you need to "Retarget" the animations. This process takes the movement from the 2K25 skeleton and maps it onto the 2K23 skeleton using Blender.
1. The Core Tool: Blender Plugin
You need a specific plugin to import and export .iff model and animation data.
The Add-on: Use the NBA 2K Blender Tools (originally by gregkwaste, updated by Trevorjpt33 and looyh).
Where to find it: Search the NLSC (NBA Live Series Center) downloads section or the EyeUC forums for "NBA 2K25 Blender Plugin" and "NBA 2K23 Blender Plugin."
Requirement: You often need specific versions of Blender (like 2.93 or 3.6 LTS) depending on which version of the plugin you find.
2. Identifying and Mapping Bones
Once you have the armatures (skeletons) imported into Blender, you will notice 2K25 has more bones than 2K23. You must use a Retargeting Add-on (like the free Rokoko plugin or the Mwni Animation Retargeting tool for Blender) to bridge them.
Common Bone Map Equivalents: | 2K25 Bone Name (Source) | 2K23 Bone Name (Target) | | :--- | :--- | | Pelvis | Hips | | L_Thigh | LeftUpLeg | | R_Calf | RightLeg | | Spine_03 | Chest | | L_UpperArm | LeftArm |
ProPlay Bones: 2K25 includes extra bones for jersey and muscle simulation. When mapping, ignore these or set them to "Static." 2K23 does not have the engine slots to read them.
