mmmm, Also, when you tie more than two brushes together they are both accounted and selected when you click on it. The entity can't be ungrouped untill you right click the entity and click on "move to world", in which will change the entity into a brush again. If you want to be able to move the bruses around, you have to set the func_details to different groups of entitys. Divide that into SEVERAL func_details. I would reccomend though that you dont func_detail an entire building, that makes the compiling ignore lighting the building. It will be litten, yes, but not with the same vigor a regular building would do.
