Poser magic. Actually, I though about that myself, But also wanting to keep the thing manageable in poser, and thinking about the kinds of shoot this may be involved in, I figured to leave ties for the shutters off. I also figured that if ppl needed them they coul dad them in post since the shutter is adjustable and a tie would follow the board to a point post effect would be the easiest answer. That and with a decent texture the shack may look busy enough that that detail may eascape the casual viewer.
