I'm still figuring out how to fill the big hole in my ship XD, and yours is ready to the point of texturing, I'm currently making the plate textures for both ships.
and I'm also trying to make a next chapter (you know whit the wormhole/portal to your world) yet, I've to make a type of fractal glass for the portal, it has to sucks up light so to say)
and I'm still working on the settings of this type of material, but you'll see.
BTW: I will also make it a separate image, so you can use the portal rendered picture to make a story from an Union Of Worlds perspective, I think that's nice for both RP scenarios.
