Hit render.
The reflections are very blurry now. This is
the effect you get on real objects from very
small bumps in the surface. To create this
effect in 3D, you could also put a very fine
bumpmap in the bumpmap slot. But by using
the glossiness parameter instead, rendering
will be a lot faster.
Play with the glossiness value to see what it
does.
Glossiness means ‘shininess’, so glossi-
ness=1.0 is 100% shiny, lower values are non
glossy or blurry reflections. There is much
confusion about this, many people will mix
up the term glossy with blurry.
