I know this has been discussed before, but I can’t seem to find any references. My furniture in an interior scene seems to be without shadows. I see shadows under the furniture, but the legs that touch the carpet seem to be floating. I don’t have a sample image yet, but I am pretty sure it is a known setting I am missing or something.
Your GI settings are too low, portals can help, if there is a window in the room a vraylight in it can be a quick fix.
