Hello everyone, I would like to simulate the behavior of a processor. When the processor pulls an item from Queue3 for processing, it will generate an empty box in Queue3. Queues 1 and 2 will have empty boxes by default. After the processor completes the processing, it will combine with the empty boxes from Queue1 and Queue2 to produce a material that contains the item. Could anyone advise me on how to achieve this? Thank you!
