Reference for the Animation Settings section of the Unreal Engine Project Settings.

Animation

Compression

Section Description
Compress Commandlet Version

The compression version for the recompress commandlet.

Increase this value if you want to trigger a full recompression of all animations. Otherwise, only newly imported animations will be recompressed.

Key End Effectors Match Name Array List of bone names to treat with higher precision, in addition to any bones with sockets.
Force Recompression

If enabled, this setting will forcibly recompress every animation.

Disable this setting before checking in your project, otherwise the Engine will recompress all animations each time the project is opened, affecting the performance negatively for all users of this project.
