Reflection probes will still show on a surface that has 0 smoothness. i would expect to see nothing at maximum smoothness on many shaders, but i was told by an experienced shader coer that this is something Unity hard coded in their lighting engine and reflections will always show. This looks terrible! i dont want to see the sky reflecting on a matte surface. And the blurring is not enough to remove the details. why not just fade it out.
When you set the smoothness to the 0, you must have no reflections…

You can try to use a black texture as smoothness map
Ive done all of those things. Theres a bug in the lighting engine. Hell, I cant even bake reflection probes anymore, it just stopped working.
