Set the following properties to control how the compression codec removes linear 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. Max Effector Diff: As keys are tested for removal, we monitor the effects all the way down to the end effectors. If their position changed by more than this amount as a result of removing a key, the key will be retained. This value is used for all bones except the end-effector's parent. Min Effector Diff: As keys are tested for removal, we monitor the effects all the way down to the end effectors. If their position changed by less than this amount as a result of removing a key, the key will be retained. This value is used for all bones except the end-effector's parent. Effector Diff Socket: Set an error threshold for End Effectors with Sockets attached to them. Typically End Effectors with Sockets are more important bones, where you may want to be less aggressive with compression to retain more detail. Parent Key Scale: Set a scale value which increases the likelihood that a bone will retain a key if its parent also had a key at the same time position. Higher values can remove shaking artifacts from the animation, at the cost of compression. Retarget: When enabled, nodes will be adjusted to compensate for compression errors, as the animation is compressed. When disabled, no node adjustment will occur. Actually Filter Linear Keys: When enabled, the final filtering step will occur, or only the retargeting after Bitwise compression. If this property is enabled and the Retarget property is disabled, then the linear compressor will do no better than the underlying bitwise compressor, and be extremely slow.
