Reflection maps are not available in all Vue versions. What Vue version are you using?
If you use an HDR map to light up your scene, the HDR map will alqso be used for reflection from Esprit and up ( dunno about Pioneer and Easel). Depending on your Vue version (Infinite and xStream, and possibly Complete), you can use a different reflection map than the HDR map.
The refmap is loaded in the atmosphere editor, effects tab, if you want to use one map for all reflective objects, or in the davanced material editor for different refection maps on a per material basis.
In the refection tab of the advanced material edotor, tick the "use reflection map" box, then click the load button and browse to the map you want to use. Click on use default if you have loaded a map in the atmosphere editor, and if you want to use this default map.
