Hey guys, is it possible to separate the individual direct and indirect components behind some refractive planes using light path expressions?

I'm fairly certain you can. the path length is a matter of how many events you list in your LPE.

hmmmm… Sorry my knowledge on this is very limited, so does that mean if i have 3 refractive planes i would have to write something like this for direct diffuse? lpe: C<TG>*<RD>L ?

If you *only* want stuff behind the refractive planes, you should replace “*” with “.” (* indicates 0 or more, whereas . indicates 1 or more)

Sorry, I misspoke: “.” isn't 1 or more, it's “+”. However it still won't work due to a bug. I'll have it fixed tomorrow.

Just a heads up on this. Whilst it wont render in the render viewer, it seems to render the sss lpe fine over the farm.
