Ok.. In 10, some of hte roids have textures that aren't where the wireframe/collsion detection is, so if you fly near it, even though you dont hit the texture, you still get hurt.

That's caused by the different Level of Detail settings you're using. The devs try to make everything match up at each of the possible detail settings, but inevitably, some little (or big) thing will mismatch, and these problems crop up.

Yeah, hehe. If you have a lower level of detail in your settings, you can fly right into the surface of the roid and pretend like you're hiding... when in fact higher detail players will be able to see you and think you're crazy.
