**yelocloud,

**one advantage would be if you have a character walk around in an environment and have the camera pan and track. The background would change 360 degrees. Also, isn't the light then "correct" for the orientation? I should do an animation with the Albany Nights probe included with Poser. It is very dark in most directions, but there is a lighted doorway at one spot. I should make V4 walk across that and see if she is properly lighted as she moves from dark to light.

But other than that.....I would prefer anyone providing an HDRI package include 4 huge, hi-res still camera shots of the four points on the compass.
