Hi all!
I've tried to use Indirect Light by just enabling it on Render Settings, and it worked... most part of it at least. But it darkened all shadows and ambient occlusions, and made the entire scene overall darken (not only shadows and AOs, but walls and ground too). I was under the impression it would only add more lighting (the indirect lighting), and not darken anything. Did I miss something? I'm using one IBL light only, and I was indeed able to see the indirect light bouncing off into nearby surfaces, so besides the darkening of my scene, it worked just fine.
