Remarks

Utility function to determine the two key indices to interpolate given a relative position in the animation

Returns

The rate at which to interpolate the two keys returned to obtain the final result.

Parameters

Parameter	Description
SequenceLength	The length of the anim sequence
RelativePos	The relative position to solve in the range [0,1] inclusive.
NumKeys	The number of keys present in the track being solved.
Interpolation	The Interpolation type of the sequence
PosIndex0Out	Output value for the closest key index before the RelativePos specified.
PosIndex1Out	Output value for the closest key index after the RelativePos specified.
Seq	The UAnimSequence container.
RelativePos	The relative position to solve in the range [0,1] inclusive.
NumKeys	The number of keys present in the track being solved.
PosIndex0Out	Output value for the closest key index before the RelativePos specified.
PosIndex1Out	Output value for the closest key index after the RelativePos specified.
