I've started work on some buildings for a mobile base and have come across a slight problem, I'm unable to enter the building. I open the door and when I try to walk in I'm pushed back out. I believe it's something to do with my geometry lod or fire geometry lod, if anyone has information on how to properly create these lods for a building to be enter-able, please let me know. This is the same problem I'm having with my hovercraft I've put on hold.
