Title: Caustics
Post by: lacilaci on 2013-03-21, 20:15:42

Will there be some sort of "feature" in corona allowing to compute caustics separately from the rest of rendering? Or some acceleration especially for that kind of effect?

I believe there is a workaround for that in corona parameters ( i think with bidir ) but after viewing the members results it's not good yet and bidir doesn't work well, must wait for it and i must say i've missed it lol

BDPT is slow and in larger scenes very memory consuming, PT+PT without limit is too slow and does do a lot fireflies...

It would've been nice if you could use the limit but still had an option to some additional effect... Like a separate calculation or so.. Don't know if it's possible. Maxwell although slow does handle caustics pretty good I think... Nvidia has also came with some solution to do caustics with Iray which so far also did only fireflies, and even though is this effect many times unnecessary and sometimes even unwanted, there are situations where is nice and sometimes needed... So IMHO not something to be really a priority, but shouldn't be overlooked.... just sayin'...
