A long while ago I, Mudd's "Tiberius One" had a load of mirror universe re-textures that were... well... eye-popping. To this day I think his Mirror re-texture of P81's Constitution refit was one of the best ship texture's I've seen.
Even though the original site (and the original P81 model) is long lost, I decided to try tweaking with the textures of WickedZombie's Constitution Refit to make something similar, inspired by I, Mudd's old work:
I've had it for a while, but haven't done anything with it in years. Thought about releasing it to the public if there's interest (and if I can get it on to Battleclinic somehow). Technically I have WZ's permission, but it's been so long since I asked I wonder if I should get it again before releasing it.
The ship looks pitch black with no lighting in-game, which I felt was fitting for a vessel from the mirror universe.
