I must admit this is my first time on the substrate thread, but I do spend a good deal of time on the lumen thread. I heard (perhaps erroneously) that colored shadows were on the list of to-dos for substrate. I was curious A. if that is in fact true, and B. if so, is there a timeline on the development?
Granted, perhaps a better question is what colored shadows refers to . In my understanding, that would essentially be refractive caustics from analytical lights, but it could perhaps refer to a different phenomenon?
