I had run into an issue with bump maps being very noisy in reflections. I searched and couldn’t find a solution, so when I figured something out I thought I would post my solution in case anyone else has the same problem.
In the textures panel, go down to the Influence pane. At the bottom is a section called Bump Mapping.
Space: defaults to ObjectSpace.
Change it to TextureSpace and the bumps should look much better in reflections.
