We sometimes have unwanted 'contact shadows' where 'pointy objects' meet the floor. For example in this shot at the bases of the legs of most of the furniture. We have tried everything we can think of, but the only way to get rid of these artifacts is to move the camera closer. The shadow seems to be always away from the camera (the position of the sun/hdri doesn't seem to influence it).
Is anyone else experiencing this? Is there anything that can be done to fix this?
