With the caveat that I could be horribly wrong, I THINK the problem I have is that it is using world delta instead of a timeline to run the Vinterp delta. Because delta world seconds runs on a 0-1 scale instead of constantly ticking upwards, it does a weird hard reset on the Vinterp which is causing the upwards movement. I’m going to play with it more and see if I can figure out what is going on with that. Unfortunately I have no immediate plans for the streams, but I’ll come up with something, even if it is fly-by-the-seat-of-my-pants week ;).
