Well, I've been able to use other array nodes to get this to work, but I am not looking at summing, or averaging my array. Build Array from set is still giving me a context error when I use it at the end of that branch I attached in the zip. I just want each character of a given id to look up its distance to closest neighbors from a different id, and then output that data to be used in a velocity blend. Averaging, Summing, all work fine, but don't quite give me the behavior I am looking for.
I'll keep digging around to try and get the array from set working, as I'm sure both you and Alok are correct and its something simple I am missing in my compound. Perhaps it is where in the tree I am placing the array from set node?
