IBL works with IDL, but it works differently than without IDL.
When IDL is enabled, the colors in the IBL are projected on a gigantic virtual sphere that surrounds your scene. If your subject is inside a close room, the light from the IBL is blocked. Without IDL, the light would reach everywhere, passing right through all surfaces.
If you are just doing a figure and it is not enclosed, the IBL light will reach it, but it won't pass through arms and legs. Thus, the shadows produced are correct.
Light-based AO is inferior to this and is ignored when IDL + IBL is used. Even if you turn AO on for the light, the renderer ignores that and uses the superior rules afforded by IDL.
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)
