Hi Michael, Using that many separate transform nodes will not be efficient. Is there a reason why you are using so many transforms in each subgraph? I think it would be best to explain at a high level what you are trying to achieve as there a number of different approaches one can take to tackle dynamic objects, but choosing which of them to pursue would depend on what you are trying to achieve.
