Just solved this with a little experimentation, turns out learning a little bit about the inspect panel in the editor is useful. But two “Get Entries Count” nodes can get the number of entries which can get then be passed to the loop, and there’s a sum node if you need a sum!
See the pic below for my implementation, where the “num” input to the loop is the number of times the loop will run. This could then be packaged into another subgraph to clean things up because the inputs to the double entries chain, and the “Meshes” input are the same. Hope this helps someone!
