Hi,
I've run into a similiar problem. I've managed to get everything working in
povray 3.7, except that i get some weird white specks.

These specks appear everywhere, but are most noticable on the main PCB. I've
uploaded a small scene which produces these specks here:
http://www.justgeek.de/stuff/povray/example.pov
The hdr file ( http://www.justgeek.de/stuff/povray/kitchen_probe_lat.hdr ) is
from http://ict.debevec.org/~debevec/Probes/ converted to a lat / long format
using HDRshop.

I've played around with the radiosity settings, but i always get the white
specks.
An example can be found here:
http://www.justgeek.de/stuff/povray/example-5-3.png (warning, due to the specks
this is 2.5 MB big)

As far as i can tell, i don't have any photons, i have used high quality
settings and there is no texture used for the board. I can't imagine that it is
a reflection from the surroundings.

Has anyone got an idea what could cause this?

Bye,
NsN
