Hi.

I've come across a (seemingly) problem combining media and photons. As a
test render, I shot photons at a hollow, fully transparent sphere with
absorbtion rgb 1 -media, and placed a (checkered) plane beneath it. The
thing is, I got some heavy caustics that don't seem to be dependent of the
media! Souldnt that media absorb the photons shot thru it? (She sphere
itself appears black).

Simen.

Is the sphere using filter or transmit? If transmit, try filtering transparency
instead.

It uses filter. I still think it's a flaw; but I cannot see why. Is the
media-photons and caustics-photons two different implementations, perhaps?
