Time for another update:
The work on the O405G is nearly complete. At the moment, the only thing I'm not happy with is the interior articulation animation - I don't think I'll be able to animate the bellows like the real O405G. In real life, the inner part of the bellows is connected to the center of the turntable - unfortunatley, I have been struggling with this for the past week and I've gotten nowhere. I might have to do something that's not as realistic, but at least looks good in-game... we'll see. But hey, you probbably won't spend much time looking at this anyway.
Also, I mapped the seat and curtain fabric to a seperate texture, to make it easier for repainters to create their own fabric textures.
