After selecting Enivornment Mapping as my Atmosphere, I loaded the HDRI file from the Vue 5 HDRI folder (under Bitmaps) that comes with Vue 5. The file is the FIRST ONE called "ChromeStudio".

The major adjustments for your HDRI scene are:

1.Sky Dome Lighting Gain. This is like a Camera aperature which allows more or less light in your Global Scene. Usually you have to adjust it UP.

2.Overall Skylight Color. This is the SECOND most important adjustment that controls "Color Temperature"- or basically the color tone of your Global Light- Warm, Cool, Sunset, etc. For POSER SKIN a subtle dark brown is a good color as it matches the general lighting used in POSER. (Poser defaults to a general Warm-Brown lighting setup.)

3. ROTATE your scene. By selecting the entire scene you can ROTATE it until the particular lighting you like hits your model they way you like. This is more tricky as every HDRI file is different and the main light comes from any number of places- or is very diffused- depending upon the HDRI file you load.
