I have currently noticed that the majority of the assets (furniture) look a lot lighter in the asset library than when is placed in Revit.
Its hard to see but the sofa at the end of the living room is the same as the second image and it seems lot darker in my model.
I had the same issue with baskets, bed and chairs.
Also can we add a different material for these library? Would great if we at least could change colours as everything is very dark.
