When creating these "packages", I was inspired by a young "Metal Gear: Solid" from 1999.
I remembered that I loved getting into those air conditioning pipes.
Although later I crossed a cable and ended up making water pipes and others.
At all times, think about the work of a company, whether it is video games or architecture, thinking about saving time and that the variables exist.
These modular kits are very easy to use in "Unity", I suppose in other platforms as well, although I did not take into account the variations in mirror mode, and you will always have to move some pieces a few millimeters, so that they are united.
