Modify an existing animation by adjusting a pose and applying that relative adjustment to a specified range in the timeline. For smooth transitions between the new pose and the old animation apply a falloff from a desired point along the selected range.

Propogate the animation from one controller onto a series of others with a variable time offset. The script copies the selected channles in the channelBox. If there is no channelBox selection, all channels will be copied. The animation copied will match the user's timeline selection. If no area of the timeline is highlighted, the entire range will be copied.
