I used 0-1 from the variable cycle trigger to do this.. and I kinda committed blasphemy (please forgive), I tied it to my custom timeline animation and also to the UI slider that controls morphs on thrust. Those Range Min/Max are randomized by Param Randomizer every few seconds, so that my animation goes between say 0-0.3 to 0.7-1 randomly. You can use more advanced approach by using sliders or whatnot. It also means that morphs are not always exactly between between set values, but depend on that randomness. Guess it's nice if you want a very particular animation of any kind... but I'm still using Autothruster to include bunch of extra body movements, and my custom expressions now are in sync. Guess you wanna use native thrust though most of the time, since randomness of motion is better.. but that variable trigger is so awesome! If for any reason you want to do something completely different, you now can.. oh man it's gonna be great for blowjob animations as well... hope you include the same feature in your dildo plugin in the future! Great stuff.
