Thanks for the quick response and looking into those!
I get all the object killing, however for my unterstanding, the seal around the emergency exit shouldn't be part of the cabin and thus not be killed on the exterior, should it?
On another note, a little idea that came to my mind regard the killing: I wonder if it was possible to make it an option disabling it altogether? With XP12, I (and probably many other users) gained a quite substancial performance headroom that could easily suck up those additional meshes without any issues and eliminate some downsides coming along with the technique.
Just an idea, maybe it's only four lines of code to happiness...
Cheers!
