Hi, I know it’s been reported as a limitation long time ago but nevertheless I’m curious is there any progress about that. I’m not talking about caustic effect itself but a strange behavior of light transport algorithm. Reflective surface with non-zero reflection glossiness doesnt project refraction from objects unless I tick “Caustic” fot those refractive shaders. Im having a project with a lot of glass bricks so turning on caustic for all of these bricks will kill my computers. A graphic explanation in the attached images.
Cheers!
I mean none-one, not non-zero 
(0,00 - 0,99). My mistake, sorry.
Just post screen of the settings, because at this point that looks like you further confuze everybody.
It’s a slightly different issue, but probably related.
