AnimSequence to PSA

[Gildor]

Hi.

There's no direct mapping from AnimSequence to psa file because psa is made with a lot of conversion work.

Original AnimSequence object consists of property data and single binary data block stored as array of bytes. This block consists of translation data, rotation data, optionally time information, and for some quaternion types - range information used for quaternion decoding. Translation and rotation tracks are pointed by CompressedTrackOffsets array. Item[0] points to translation data for 1st bone track, Item[1] points to rotation data for this track, Item[2] points to translation data for 2nd bone track and so on. Interpretation of track data varies depending on TranslationCompressionFormat and RotationCompressionFormat fields. Presence of time track controlled by KeyEncodingFormat variable: AKF_ConstantKeyLerp distributes keys uniformly in a time interval, AKF_VariableKeyLerp tells engine that each track has either 1-byte or 2-byte time values (depending on the number of keys).

AKF_PerTrackCompression tells that data stored in more complex format which I don't want to discuss here (because of complexity). By the way I suppose that Mass Effect 3 uses older engine version which doesn't have AKF_PerTrackCompression key encoding.
