wow, bake some normal maps for this. 6.5GB of render memory just to stick a couch in your scene. There is really not that much detail for having 8.5Million faces.
Way too many faces. My oh my, stopped blender for a few seconds when trying to scale this thing.
Thanks, great model, surely will come in handy.
