thank you!
the polycount is rather hicg on the bed and all furniture as well - though lighmass calculation takes some time in “hacked” (check koola’s thread for this) production mode.
bed is around 800k - could be a lot more less, that is true if lot of time spent on optimizing - but i fear the detail would lack then.
moving through the scene is very good with good framerate, but it is not that large after all 
sorry, I would have to figure out but in the near future i am sure to be able handling that
cheers
