Yeah, I started to do that, but it turned out to be non-trivial. When you switched to the interior view and tried to move around, it was still moving the external camera. I poked at it for a bit, but figured that we might as well leave it for #3015 which is get rid of navscene completely.

On the other hand, if that's all caused by not having a shared navObject, that might get fixed by all this. I don't suppose you can help with that? ;)
