1 pointThanks again for all your help with this. I'm starting to understand expresso a little better now. Here's a scene i was able to create by adopting your layout. Sketch_062916.c4d My expresso group is far from elegant though. basically I had to copy the entire chain for each segment and reference a different hierarchy each time. I also had to add in increments of ten on each chain to the index output of the object index node before sending it into the point index input.
