i found a few threads on setting up caustics in yafray, yet have absolutely no luck with it! i set my photon light EXACTLY like the examples ive seen… and with the materials, i turned caustics on, the color things too, and tried numerous varitions on the attributes buttons… very numerous* i still CANNOT get caustics to show up!
it bugs me so…
my floor has caustics enable as well to receive them, and all objects have all the attributes i seen in examples… i dunno what im doing wrong here…
could someone maybe post a few pics for me, one of the settings for a glass object to emit caustics, one for the floor to recive caustics, and one of the photon light settings? or u could just write them all… i spent the past 4 hours turning on and off attributes for every object to see if somehting, anything would work… but nothing yet =\
am i doomed to render plain glass forever?
