Thanks for the link and for the additional explanations.
We’ll add a setting that makes the viewer use camera height (above floor or ground) from the initial view for all the remaining views, ignoring the height configured for the remaining views. We’ll provide more details in this topic.
As for the balcony railings, you are right: a railing doesn’t stop the camera to pass through, because the camera is modeled as a small sphere. For such cases we suggest to add fully-transparent planes that block the movement. It’s good to set “Lightmap resolution” in the “Objects” tab to 0 for these planes, so they won’t take lightmap space.
