I'm not sure that any of the aforementioned are causing the "stepped" behaviour with MP. Certainly, a/c using big textures cause meltdown on MP for people with older graphics cards (like me). But as several people have noticed and mentioned on the IRC channel, even ordinary AI aircraft move in a slightly "stepped" fashion, identical to MP aircraft, which move this way seemingly independently of the rate of data transfer. Does this happen with barebones, low-poly, low-texture, no-cockpit AI models too? I suspect they're not any smoother - I'll maybe get time to test that later on. > Only problem with removing pieces from an aircraft model when it's further > away is the zoom function - it's not going to look good viewing a model > with bits missing - unless of course the "pieces" become visible again on > zooming. That's a good point... personally I think hiding parts with LOD is a good way to go, but parts hidden should be almost entirely internal ones which aren't going to be seen anyway. I know on my model there are significantly more vertices and more texturing in the cockpit than on the whole of the external model. That might be more a comment on the poor quality of the external model, I don't know :-) > I was also wondering if there is a unified set of XML files for each > aircraft.

Every aircraft has a -set file which specifies things like the FDM config and the main 3d model XML files to be used and some other bits and pieces. Beyond that, we have almost complete freedom to structure the aircraft model as we like, with a tree of XML files managing various bits of the 3d model, and nowadays usually a nasal script or two. Despite having followed the fgfs project for many years now, having started to build a model myself I have been amazed at the flexibility that is there...
