I have to add that tent / building can be either an object or a zone mesh, basically, all buildings post luclin are object and all buildings pre luclin are zone mesh. When new luclin engine came out, SOE decided to use more objects in zone, to reduce FPS i guess, and the good thing is it reduce considerably the time needed to build a zone, since you only have to do the ground mesh and then add all the objects (Tree, Buildings, Beds, Rocks, ...).
