Hi, I'm modifying the Trade-Fed battleship (which is labeled as a coreship for some reason) that was in the mod tools bunch of mesh files. So now I'm going to change the look of the engines and the command bridge to match the objects from the battleship. I'm also planning on making the command bridge available to walk through until destroyed. Is there anything I need to know before I change the looks of the engines and command bridge in blender? I just wanna make sure what files I will need to modify for the destroyed model for things as well as have everything working. Thanks

All I can suggest is going to Wookieepedia and getting a lot of reference pictures. There are SW cross-section books out there, so if your library has the one from Episode 3 consider checking it out. Or go to Barnes and Noble.
