When you play a BF2 space map, you'll notice these giant shields in the hangars that prevent bullets from coming in, but allow ships to pass through. However, when I place them in BF1, they aren't letting the ships through. How would I change this?

I don't have the shield odfs, but I imagine the easiest way is to remove the vehicle collision lines. If it's similar to the Faamba shield, I'm not as sure....

there is vehiclecollision, ordnancecollison, soldiercollision, (groundcollision and buildingcollision) wich you can define in odf, if i looked at the right odf there is soldier and vehicle collision = clear, maybe bf1 engine doesnt know this command

It does, I just got it to work with the VehicleCollision = "Clear" line. Thanks for the help.

no problem
