Ah, what I misunderstood was that you meant using IBL, well, as an IBL. As Just A Stupid Light, it works. As an IBL, not so much. Agreed. And, yes, I did understand that. I do occassionally find it useful as Just A Stupid Light, definitely for lighting a preview, and even, very rarely, as a light in the final render. Otherwise I don't use IBL as an IBL, probably because I always use Superfly.

And hopefully though I've explained that my post about using CPP to control my lights is not particularly related to the issue of IBL. Ya don't want IBL, don't drop the dials onto the CPP.
