I have a mesh if you want it. It's not this one, it's one that was used to create a 1:1 model in Minecraft. It's lower quality, as vnm51 has done a great job here and the mesh I have is (I assume) ripped from the game, but depending on how it's used, it may work
From what I understand (from interviews with the designer of the game), it's only the character models that they render in movie-quality and then shrink down. When it comes to ship models, they actually produce them at the same size that they go into the game. That means that your model is probably the highest quality Odyssey class model in existence right now. Well done.
