    What exactly happens to the animation when this option is enabled for importing animations?

    Obviously it reduces some key frames somewhere, somehow. But it's there a pattern or algorithm or something to it? There's not really any information on it in the documentation.

    Basically key frame reduction will simply go through all key frames in your animation, and evaluate the animation curves with and without that key, and if the difference is smaller then some defined delta, the key is removed.

    So by that logic, if an item is keyframed, but doesn't change it's values, it's deleted?

    When exporting from lightwave, i find it's best to simply keyframe everything every frame to ensure that the animation in unity is as accurate as possible. but i get worried about the overhead of all the keyframes.
