Hey
I have spent a lot of today trying to work this out and i think i have a solution. Mark when i tried your way it wouldn’t let me track the 2 geometry points to 2 different objects.
i.e point 1 follows first dot up and point 2 follows a second dot down.
So I animated the dots and then baked then selection creating a mov file with my animation. the i could track the dots as one object. If there is a more organic way to do this i would love to know because this feels like a work around.
