face_off documented a process using some tools that makes an infinite light set automatically by analyzing your lat/long image. If starting with an IBL probe, you must convert it to lat/long first. If you're using my EnvSphere and GenIBL, we go the otherway, starting with a lat/long image and generating an IBL probe.

HDRShop can go both ways. But GenIBL works with props and Poser lights, too, not just photos. Anyway, you can start with GenIBL, then HDRShop the result.

However, he links to the key element called the "light gen plugin" for HDRShop. The link is dead. I don't know if it is still around or not.

This is quite an involved process, so if you thought my sun-matching steps were time consuming, don't even bother reading it.

Follow the link.

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)
