Hi,

Not getting the expected results from using photons, for example 
"scenes\advanced\optics.pov" and a couple of my own.

Has something changed?

as compared to what version ... if you were using v3.6 there are a 
number of changes that might be the reason. A little more info would be 
helpful ;-)

POV Ray 3.7 RC5, Windows 7 64bit

Some of the the light beams in optics.pov are missing. Tested on Windows 7 
64 and Ubuntu 11.10 64 and 32 bit versions.

I did a little trouble-shooting ... swapped (mirror and lenses) textures 
around and indeed there seems to be somethings that's not correct. I 
don't think it's the objects or textures, so I started playing the 
photon global settings and saw slightly different results. Admittedly 
I'm weak when it comes to photons, but /think/ that's where the problem 
is ... maybe someone a bit stronger on this topic could lend a hand.

I looked at it too. It works with RC3 but not with RC4 & 5. Even with 
version 3.6

Thanks Stephen ... that narrows it down a bit. I looked in revision 
control and didn't see anything photon related, so perhaps that 
eliminates the obvious. At the very least I think we've proven that 
something is fishy. I'm going to submit a bug report.

As an aside Jim, I tried to look up "SSLT" in the index of the help 
documents. Nothing was found, I had to look up "subsurface". Maybe an 
additional entry in the index would be useful.
