First, great image, Zhann. Second, I am also having mapping problems (now that I know what sphere I'm supposed to be mapping). If I take a regular rectangular pano and map it spherically, it comes out distorted (and the two ends of the pano don't match up at the equator of the sphere). If I use HDRI Lab to make a spherical distortion, and map that (spherically), I get a HUGE artifact where the two ends of the pano meet. I've not yet tried downloading images from the HDRI site simply because I haven't a clue in hell how those would be mapped to the sphere, and if Zhann doesn't feel she has a handle on it, then you gotta know I'm really out in the fog.

Could be worse, could be raining.
