In hindsight, this might be a bit of a cheap shot. But taking DAZ building models that are designed for either interiors or exteriors but ALWAYS as intact and make them appear broken is reeely difficult. In the end I just cobbled together pieces of debris and some falling bricks (which seem quite big by comparison) and called it a day. I hope the result is still satisfying to you!
Go follow me on Twitter: @UnseenHarbinger! I tend to publish WIPs and other stuff there, which I don't tend to upload anywhere else (because I'm lazy).
