The new Room Creator expansion gives you a complete range of staircases and balconies to use in your scenes. There are 10 figures and 20 props, including spiral and straight staircases, a folding ladder (ERC-controlled), an interior gallery, a wooden balcony, a stone balcony figure and several single/double-width balcony props.
There are also industrial pieces - a fire escape figure and prop, a metal walkway, loading ramp and stairs, along with a fire door and 2 shuttered grills for loading bays (also ERC-controlled), plus a set of 3 scaffolding units which can be built up to any height you like.
All the figures can be configured for different room setups, and there are 36 poses included, plus 18 MATs. The figures and props all have .DSA files for loading materials correctly in Daz Studio.
