Also the question to GPU gurus: I think most aircrafts that have hi-res liveries do so because of several small signs here and there.  So does it makes sense to have a lo-res opaque texture that paints aircraft's body, and then a hi-res transparent one that places signs on top of the first?  This way hi-res texture will be mostly "empty" - will it substantially improve GPU cycles and memory usage?
