Eric, my apologies, you're absolutley right.

Photoimpact is great for creating evenly exposed 2D images from bracketed camera shots but the ".hdr" files it creates are not liked by Vue 5 at all. Maybe the next version of PhotoShop.....?

Great little tutorial for HDRI generation on the cheap at the above URL.

Cheers,
Mark
