I'm using POV-Ray to generate a synthetic lightfield for a school project.
I've run into an issue where I wasn't getting bounced light where I
expected it. After a commenting out a few different things, it seems that
the specific problem involves radiosity samples through objects that are
refractive and reflective with conserve_energy active.
here's renders with conserve_energy on and off:

and here's the scene file:

Can this be fixed in the scene file? If not, is there a source tweak that
could fix it? I've poked around a bit, but finding the right loop in that
mass of code has repeatedly proven tricky.
If you're wondering, in the real application the "light source" is a sphere
around the scene with a custom pigment on it that samples our incident
lightfield and the scene is a bit more creative ;).
