Description
Find the two frames closest to the given time. InterpolationFactor gives the position of the requested time slot between the two returned frames. 0.0 => We are very close to OutFrameIndex 1.0 => We are very close to OutNextFrameIndex If bIsPlayingBackwards it will return exactly the same indexes but in the reversed order. The InterpolationFactor will also be updated accordingly
