I dont know:( i made this scene "renderable" after 20 minutes of fight ( last 20 minutes). I deleted all books, all table ware, all flower and other addons, and next i put Corona Sun again, and now i have pure scene only with furnitures, and scene is rendering ok...but looks empty, no addons and other details...I will try to use a little script to turn off all materials which are trying to add displacement to the scene...I have no chance to check this scene click-by-click if displacement is turned on i n materials (scene consist over 500 materials).
