This is not strictly caustics, but simply colored transparency, and as has been pointed out, I've been told by stewer that Firefly can do it. A caustic is a focus/defocus of otherwise near-parallel light beams from the source, causing localized variations in luminance that don't obey the inverse square law.
Color transparency could be performed easily if only the Poser Surface "Transparency" channel was a color instead of a number. I can't remember why this was not exposed. Might be in a future version. The code is already there.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
