Custom written Blender addon to import LivePose adjustments made ingame through SimpleHeels onto a Blender armature and animation timeline. Allows making precise LivePose adjustments truly permanent very easily through a simple Export - Apply - Import - Save.
Why not just stick to LivePose? LivePose applies a simple offset to bones, but these offsets are neither permanent (when switching through animations, you're gonna have to manually delete / repply them), nor do they update aspects like physics interactions with the rest of the body. This addon gives a way to solve that issue, making actual customization of animations possible without compromises.
The description in the repository should cover how to use this. Naturally requires some knowledge on how to import and export animations from the game (either VFXEdit's PapEditor (recommended) or XAT), but should be simple to use even without extensive Blender knowledge otherwise.
