How to have one layer hold a mob while another person can walk right underhim in a diffrent layer. Used maybe for second story houses and such. Ok ok ok I giving credit to Lord Raven I wouldnt have even known it was possible if I wouldnt have seen it on his game.
Sure I know the code with the invisas and the roof deal but I dont know how to have 2 storys of a house so the 2nd story someone can walk under while your still in it.

Any one know? lol besideds Lord Raven :)
