On the left, my Poser version of an actual IES light. On the right, the same light in the IES viewer.
The IES viewer presents the light against an invisible (and ambiguous) wall and an unspecified camera focal length. As I cannot determine the exact configuration of wall, light, and camera, I am unable to exactly match the light pattern. Also, I think the IES viewer is not dealing with gamma, and is darker than it should be.
So - I do not yet have exact visual confirmation that I'm doing it right, but everything is directionally correct. Every light I try produces the right features.
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)
