Quote - I guess the way you rotated he hole answers the question about the modifing the direction of the light hot spots.
Yes you rotate the sphere, not the image. The sphere is an actual prop with the actual image on it. You can look right at it.
Since many HDRI are not very H and need help from a light, I usually make a spot light, parent it to the sphere, then switch it to infinite. Then I line up the infinite with the apparent position of the sun on the sphere. (Tricky - you have to set up a camera with the right sight-line through the world origin. Then you line up the infinite light indicator with the picture of the sun.) Once this is done, you can then Y-rotate the sphere and the infinite light will rotate with it.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
