The reflection is set proportional to the shininess of the material. Thus by
varying the material shininess value over or between objects the amount of
refection can be controlled. The overall amount of reflection may be
adjusted by the use of <refl_correction> -1.0 (fully transparent)- 1.0 (fully opaque).
