No, that won't work unless you can guarantee that the offset value will always be within ~100m of the viewpoint. The problem isn't that the offset exists, it's that it's being pushed onto the matrix stack twice -- once to draw the terrain, and once to "undo" it to draw the aircraft model. The model must be drawn with its own viewpoint-to-origin translation, and shouldn't care about the terrain's origin. The terrain translation is too big, and causes FPU/GPU precision problems at scales the aircraft model cares about. Andy -- Andrew J.
