The repeated values are shifted so that each repeated portion has its first value set to the last value of the previous cycle. If the start frame is less than the end frame, the animation will cycle forwards. Otherwise, it will cycle backwards.
This function is the same as hou.cycleoffset() except hou.cycleoffset() accepts frames instead of times. If you want to repeat motion exactly, use the hou.cyclet() function instead.
This function is one of the special animation functions that use the current playbar time and information in the parameter’s keyframes, such as in and out values, tangents, acceleration, etc., to evaluate themselves. Because the information needed to evaluate these functions comes from the keyframes, these functions take few or no parameters.
Calling this function from outside a parameter’s expression will raise a hou.NotAvailable exception.
