Here you can define a list of animation bone compression codecs to try when compressing bone data in an Animation Sequence. The available Codes are as follows: Anim Compress Bitwise Compress Only: Focuses on Bitwise compression and retains all keys. Anim Compress Least Destructive: Restores any present animation compression to raw data. Anim Compress Per Track Compression: Focuses compression to a per- track basis, and compresses each track individually. Anim Compress Removes Every Second Key: Removes every second key present in the animation. Anim Compress Revolve Linear Keys: Removes any keys that are unchanged from surrounding keys. Anim Compress Removes Trivial Keys: Removes any keys where position and orientation of Assets are unchanged from surrounding keys. Empty entries in the list are ignored when running bone compression on the Animation Sequence. However, the list must contain at least one codec in order to compress the bone data.
