Overlap, specify Tiled model that cover other Tiled Model?

I load several tiled 3D models in the same viewer. I can display all the tiled models without any problem. Some of them have overlapping boundaries and the display is not clean (mix of 2 models…). Is it possible for tiled models at the same altitude, and which overlap, to specify that one model overlaps the other on the overlap area ? specify the model that should cover the other in one area. For example a kind of hierarchy of display layers of 3D Tiled Models. Thank’s for advance.
