I just need to know if there is the option to make a vehicle clip, similar to a player clip, used on areas such as modeled stairways to prevent the biped from catching on the edges. I will be having an area with ladders from one level to another, but I do not want any passing vehicles on the upper level to fall into the holes.

I am just wondering if I can make a surface that only prevents active and inactive vehicles, but not bipeds, munitions, dropped weapons, and spent shells from passing.

I will lock this thread once I get an answer as to not clog the tubes of the interwebz. Thanks!
