I disagree. Look at Suzanne in the pic at the top of this page. The 'caustics' are basically just a projection of the Suzanne shape onto the ground with some bright spots. So fake. I don't care that the caustics aren't real, but they should at least look convincing. Or Indigo. :D

He told me exactly the same thing that olivS pointed: that needs photon mapping, so is a completely different approach. Reflective caustics are not possible with this technique. I'd like to see this patch in 2.44 though. I asked RCruiz about reflective caustics a couple days ago.

I think I'll wait for the real thing (like already in YafRay). Fake caustics are nice for animations and so, but for rendering stills you'll definitely need real caustics.

It seems the caustic patch result is the same as POV-ray's fake caustic for transparent materials: you'd need photons to do reflective caustics at all, while fake caustic looks like enhancement of the transparent shadows... Perhaps I'm wrong, I didn't try the caustic builds yet ;) @toontje: I don't think so.

And if a highly complex shape is casting caustic, there is no practical way to determine if it is fake or an accurate simulation. And simple shapes seems to cast accurate caustics, so for all intent it looks good. One question though (I should really ask this in the blender forums...): does this patch allow reflective caustics? Like the heart shaped caustic cast inside a cylinder? Quote: But it's not good when so can see so easily that it's fake :(

well done RCRuiz
