Quaternion interpolation mode

Export > File Type Specific options > Include > Animation > Extra options >

Use the Quaternion interpolation mode menu to select how to export your quaternion interpolations from the host application. Select from the following three options:

Resample as Euler interpolation

This is the default conversion setting for quaternion interpolations.

This option converts and resamples quaternion interpolations into Euler curves to ensure interoperability.

Retain quaternion interpolation

This option retains quaternion interpolation types during the export process.

NoteUse this option when you export animation that has quaternion interpolations. This option is only compatible with applications supporting this interpolation type, such as Autodesk MotionBuilder. Also note that the resulting animation will not be identical since quaternion evaluations are different in Maya vs. MotionBuilder. Use the default option (Resample as Euler interpolation) to obtain visual results identical to your animation in MotionBuilder, or other applications.

Set as Euler interpolation

This option changes the interpolation type of quaternion keys to a Euler type, without resampling the animation curves themselves.

NoteUsing this option results in the same number of keys, set as Euler types. The visual result will be different since it is now evaluated as a Euler interpolation. Use the default (Resample as Euler interpolation) option in order to obtain visual results identical to your animation in MotionBuilder, or other applications.
