I think it's because your bump is so extreme - some of the rays are getting reflected through the surface and it's so close the rounding lets it through rather than hitting.
Cheers,

Hi list,
we've got a strange reflection behaviour with bump-map.
have never really noticed that before...
see atteched image.
the yellow ball shouldn't be visible in the grid!
the phong material of the grid isn't transparent.
Anybody noticed the same or are we missing something obvious...
Thanks,
Juan
