I have flowitems traveling down a network node path with delays at various nodes. I'm wondering if there is a way to make the 3D visuals more realistic? Right now when two item arrive at the same node they take up the same exact space in the 3D vies. I'd prefer it if they positioned themselves in a sequential line with the first flowitem to that arrived sitting at the front(similar to how they would stack in a queue). Does anyone have any suggestions for how to accomplish this? I've attached an example model to the question that shows the behavior I'm talking about.
