Set the following properties to control how the compression codec removes trivial keys from the animation data: Max Pos Diff: Set a maximum position difference to use when testing if an animation key may be removed. Lower values retain more keys, but yield less compression. Max Angle Diff: Set a maximum angle difference to use when testing if an animation key may be removed. Lower values retain more keys, but yield less compression. Max Scale Diff: Set a maximum scale difference to use when testing if an animation key may be removed. Lower values retain more keys, but yield less compression.
