Set the following properties to control how the compression codec operates for each track: Max Zeroing Threshold: Set the maximum threshold to use when replacing a component with zero. Lower values retain more keys, but yield less compression. Max Pos Diff Bitwise: Set the 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 Bitwise: Set the 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 Bitwise: Set the maximum scale difference to use when testing if an animation key may be removed. Lower values retain more keys, but yield less compression. Allowed Rotation Formats: Set which encoding format the per-track compressor is allowed to try on rotation keys. For available options, see the Compression Format Reference. Allowed Translation Formats: Which encoding formats the per-track compressor is allowed to try on translation keys. For available options, see the Compression Format Reference Allowed Scale Formats: Which encoding formats the per-track compressor is allowed to try on scale keys. For available options, see the Compression Format Reference
