@srek So I was intrigued to try it with nodes but the first thing I try to setup, of course, doesn't work, I replaced the keyframes with a target object, it kills the memory node for some reason, it doesn't output the previous state, things like this frustrate so much 😞
I am pretty sure the setup is somehow wrong, but it shouldn't be, looking at it, it is so logical.
