So, what you're saying is that this might make it possible to have a very high resolution skin, say by having a seperate 1024x1024 BMP for each part of the aircraft?

Yes. Its possible for default skins. In fact, its been used since the early versions of iL-2/PF with propellers and other parts that were textured on another file inside the sfs containers. So if we want a mega-hi res skin for a given aircraft, it's just a matter of remapping the 3D model to several texture files, and load them as the default skin.

Now for customs skins, we gotta understand how the engine loads the skin bitmap, and try to get it to load more than one texture file "on the click".
