PARAMETERS: There are two forms of cube map texture:- vertical cross and 6 images.
Either can be used - alternative forms are shown in <parameters> and in <texture-unit>
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
