This was my first full creation in Marble World. I did a similar concept in Boom Blox years ago, where you would see the process of a product getting made, however in reality each machine was just looping its own materials. When I began work on this, Patch 0.1.25 (Logic Part 3) (the factory update) hadn’t been released yet, nor logic. After these were released, I re-worked my creation to use them.
Originally the marbles were simply going to teleport back to the start of their respective machine, however, after logic was released I was able to create a more convincing effect where the next stage of the marble was spawned after the previous one entered the machine and was deleted. This meant that when the machines started, you could “follow” the first marble through each one.
