The Unroll filter is used to remove gimbal locks. This filter requires 3 rotation curves in the same Apply call. This filter expects to work with interdependent curves. The curves are expected to be in the X,Y,Z order regardless of the node’s rotation order. The rotation curves are unrolled with priority on the Y-axis… or whichever curve is in the second position. See attached file FBX SDK FAQ.pdf for sample code.
