EDITED: sorry, nevermind! :dry:
Yeah, looking forward to :woohoo:

Yes, the room is several meters wide so viewing it from 20m distance makes sense.
My first thought was that the z value which is 1.0f hardcoded gets multiplied by 1 over some mete…
Could the problem with the scaling calculation could be that you are mixing real-world-meters (di…
