The meme won't die. I have written many times IBL + IDL is great. IBL+AO is old school.
Thing is, though, that if you have walls (or EnvSphere) then IBL does nothing because it is, by definition, outside of all your scene geometry, on a virtual sphere infinitely far away and infinitely large.
There's nothng wrong with that. It's simply not going to light a subject that is completely surrounded by geometry that is visible to raytracing.
I also showed that, when properly constructed, you can get identical lighting from my EnvSphere and from an equivalent IBL.
The images, however, are completely different format. (UV layout)
Angular map, versus equirectangular.
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)
