I have been trying to make a mission where SPAA shoot at targets from the roof of a building, however, no matter what i try to do, it doesn’t work and the spaa still phases through the building to the terrain floor. I have been trying to place objectGroups below the roof to try and keep the SPAA on the roof, but it still phases through. I have an area above the roof to teleport the SPAA onto. during the teleport, it phases exactly the same to the floor, as if the buildings or structures were never there.
