Attached Link: Probelight thread discussing image lighting, mapping formats and Sphere_Map node

In a thread about the probe light I discussed this technique. Here's a screen shot. Follow the link and scroll down to post #44 to see discussion of the sphere_map node.

Please pay attention to this: IBL probes are in angular map format. This is not the right format for the Sphere_Map node. The correct format for Sphere_Map is latitude/longitude. These things are discussed in the linked forum. You can convert to LL format using free utility HDRShop.

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)
