A flattened sphere hovering over the ground.
The only light is an IBL.
On the IBL, shadows are disabled. AO is disabled.
On the sphere, Cast Shadows is disabled.
Yet there is occlusion under it. I don't see what else there is to say about this. The only possible conclusion is that IDL looks to the first opaque surface and that's where bounced light comes from. If it never reaches a surface, then bounced light comes from the IBL, "mounted" on an infinite sphere enclosing the scene.
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)
