The main hub is well on it's way! Most of the machines will be placed within the 4 huts (some for automation and some for manual use). A little pixel art to correspond to the wing that will branch off from each side.
The letters look upside down from outside the huts, but there will be a roof in place over the whole platform eventually
The lower structure will be the fluids room (soon to be fully enclosed). It will eventually house twenty 7x7x8 steel RC tanks. With a floating structure, I had to build in some behind the scenes buffer room on the top/bottom/sides for pipes and associated machines. I'm thinking of using illusion blocks to allow hidden access to this space for tweaking.
It does look good with open bays, but I plan on closing it up once I devour another volcano. Makes it easy to access while I'm building inside.
