Walk underneath and ontop?

[MrOmega]

I've been able to accomplish this but the downfall is it would only look correct to the current player and not others.

My method involved 3 NPCs two npcs would adjust a custom var like client.walkLayer and if it was 0 i would have the 3rd NPC draw above the player and if it was one I have it draw below the player. But since this is done client side it only shows correctly to the current player. I did this long ago and I can think of a few ways to improve it now. But, I don't know any sure fire way to do it.
