Yeah, sorry, I should have made clear that the story that I tell in the post is not contained in the linked paper. Rather, it’s a story that David Bau sometimes tells during talks, and which I wish were wider-known. As you note, the paper is about the problem of taking specific images and relighting them (not of generating any image at all of an indoor scene with unlit lamps), and the paper doesn’t say anything about prompt-conditioned models. As I understand things, in the course of working on the linked project, Bau’s group noticed that they couldn’t get scenes with unlit lamps out of the popular prompt-conditioned generative image models.
Ah, thanks for the clarification! That makes way more sense. I was confused because you mentioned this in a recent conversation, I excitedly read the paper, and then couldn’t see what the fuss was about (your post prompted me to re-read and notice section 4.1, the good section!).
