Sorry, I thought you were asking about area lights (missed your bold text in the quote).

I honestly have no idea how it should work. All I know it that at present our IBL's in Poser only influence the diffuse aspect of any material when using HDRI's, and it'd be nice to have access the specular as well. Maybe this just won't be possible in Poser (or maybe I don't understand HDRIs.
