I can see what you are saying...but the aircraft (in the cockpit view) is actually a different scene graph. Really I've got to get more into ssg to understand how all this works better. For some reason I seem to have an easier time understanding the lower level opengl stuff now than plib (which probably sounds backwards). My first concern would be about the overhead of transforming the terrain each frame (lots and lots of vertices). If it can be done, I think my earlier suggestion of rendering the Cockpit with no position offsets might work. Can't we render everything else and then lastly set the camera to the pilot's nose ( ie with only the offset from aircraft origin and no position offsets or orientation rotations applied). In other words just render it on top of the rest at 0,0,0 plus a little offset to the pilot seat so the cockpit looks right? Or is changing the camera like that not allowed? Note that if we did this we would still need to apply the view offsets so you can pan view and look down at the ruder pedals properly.
