@Baron Xot Whoops that was my fault, fixed that bug now thanks for finding it ! :)

Can make and use the alien alloys but they don't seem to be storable in storage or stockpile zones, can anyone else confirm?

excuse me, i just didint play in an while and i kinda forgot about that
but on the image the hull of the craft is white purplish and not fully purple

That's the image I pulled the colour from, I literally did a colour picker on that and used the rounded values, there's no way to get it to have the proper gradient that it does in the original game so have to just pick a colour from the wall somewhere, that's why the tiles are lighter so it could be more like the floor tiles in game.

if i recall the ufopedia picture and craft hulls are more sliver colored

They are in the original game, I literally did a colour pick from the game on my own PC.

nigga why are the alloys purple

New update: Changed colours on tiles slightly, brightened the Alien Alloys Floor and made the Aqua Plastics floor green to match the aesthetics of the alien subs better

make the alloys steel esque like in the original game

check the discussion i added for some ideas of other ways of adding your resources.
