so, with the latest update to timeline, its possible to add in vibration morphs as a subscene, I have the improved impact morphs as a subscene and some walking morphs as a subscene to add some jiggle to the thigh, stomach, arms (i just did the arms for the impact morphs) breasts, idk, I have the morphs but, my feeling is that you can do physics settings which directly compete (do a better job vs) breast morphs.
