The only Galactica model I have right now is from the Galactica packet on Battleclinic. Though it looks OK on appearance, it has a texture tiled across the entire hull which makes it impossible for a proper retexture. Also, some areas of the Galactica's head are innacurate, and the nameplates are poorly done. In all, it's a pretty bad retexture. On top of that I don't know where all of the hardpoints are to make a proper UI.
And i'm talking about the "origional" galactica, as I refuse to acknolwedge that the sci-fi channel's monstrosity has anything to do with one of my favorite stories.
The other "battlestar" in the packet is the Rycon, which was textured from concept art. I'm happier with this one, probably because it was never official, but since I don't know where all the hardpoints are It's impossible to make an accurate SFC translation (The Rycon has a pair of BIG GUNS in the nose, and I'd like to stick PH-4s in there.)
So yeah, a Better Battlestar is on the wishlist, but I'd settle for any way to alter the hardpoints or at least find where they are without an expensive graphics editing program
