Halo 2 Anniversary Forge on Nebula

Long story short, why in Halos name does the map Nebula have stone pieces in space? How is someone supposed to make a non-stupid-looking spaceship if every piece in forge looks like it was sculptured from dirt. At least in Halo Reach the pieces were able to be made into anything including visually. I just had an idea for a ship and in no way am I considering making it if it has to be in a stone texture…

The point I am trying to make here is that they might as well have not even made an empty space map because no pieces even look remotely connected to the map. I appreciate the effort, but it is pointless.

They are on every forge.
