The sphere you see below is lit by a single sun from the left (true highlight). There is a secondary “false” highlight caused by the surface reflecting back the world colour. I want to get rid of this false highlight. The only way I have succeeded, by making the object shadeless, also gets rid of the “true” sun highlight, which I want to keep.
I’ve tried different settings without success. It’s a yafray render. How do I make this object stop reflecting the world colour?
