Hi, I still have problems what you mean with "crease angles" - do you mean how smooth you can get a object?
I noticed that .ac need more vertices to get a object smooth and roundly. I did some experiments with .osg. Interesting: it is rendered like you see it in Blender. I think .osg is a good start for FlightGear-OSG, ist has several features we don't have with .ac. like cube mapping, embedded shaders and so on...
