Looping ability for Value Clips

[marcelreinhard]

Hello,

since ValueClips are the go-to solution for keepAlive animation, we are missing a mechanism to define a looping behavior.
A direct use case has been discussed in the forum.

It seems to be sufficient if the implementation derives the interval-to-loop from either the "times" field or "templateStartTime/templateEndTime".

Thanks a lot !
Marcel

Thanks, @marcelreinhard . Just wanted to clarify:

1. whether the ask here is for both fixed iterations and infinite, or since it's pretty easy to apply a clip multiple times, just infinite at the ends of the specified range?
2. Is the looping simple such that from the end pose of the looping clip we transition exactly to the first pose? Noting that TsSpline's infinite looping supports additive offsets so that you can use looping to make a character walk down a path forever. But that relies on very granular specification of the looping behavior, which would minimally, I think, decomposing your clip into a "simply looping" clipSet and an "additively looping" clipSet, and keeping the two in sync. Would obviously be simpler if simple looping suffices.

Thanks!
