ScrumbleShip is the most accurate space combat simulation devised to date. Gather resources, construct a capital ship out of individual blocks, then pilot it with AI or human help against other players.
The GPU lighting is coming along excellently! There's still a few quirks, but it's capable of rendering most ships reasonably accurately.
Discerning eyes should be able to pick out two minor lighting bugs in this image! +10 points to the first to spot each!
It looks like lights are lighting up faces of blocks that aren't directly being hit by light. As seen on the sides of the green plastic blocks in the top-middle.
The second bug... Blocks not lighting at all when they should? I can't tell if those are unlit blocks or just a darker material on that one metal box on the left.
