Make walkable tiles out of your BobAngels metal plates.
Got too much bare earth and an overabundance of, say, nickel plates? Keen for that minty Lithium colour? Upset that cobalt plates have absolutely no use whatsoever? Penchant for pixel art? Wanna sort your factory wings by colour? Need to really feel like gold is a substance that is beneath you?
Naxtiles.
Original tile art from Yuoki Railways (no license), modified to match the plate colours of BobAngel's metals. Metals without plates will allow you to craft tiles from ingots (Manganese, chrome). All tiles functionally identical. This mod uses some 25-27 tiles, fair warning.
This is my first mod, so it's neither complicated nor functionally rich. Still, pretty floors, right?
