I know, I realised this just after I'd posted!

Thanks for that idea, it worked pretty well.  Except that some of the
"colour" of the blob was actually due to the colour of the plane.  Anyway,
after a bit of tweaking I came up with this, which is far closer to what I
wanted.

pigment{ color rgb <1,1,1> }
   finish {
         diffuse 0.5
         ambient -1.1
      }

Cheers!

Scott

Would you be willing to post the source for this image?  I think I could learn a lot
from your work.

No probs, its in p.b.s-f now under the same subject.

Hope you can understand it, it's a bit messy!

Where would one find or how could one generate the Myphotons.ph file that is
called in your scene?
thanks.

Hi, if you remark that line out, Pov will generate the photons...

Yeah, sorry about that.  If you change it to "save_file" it will generate
the photons and save them to a file (this will take a while before it
actually starts the rendering).  Once you've done this you can change it to
"load_file" and it won't have to calculate them again.  You are then free to
fiddle about with the textures and things without have to recalculate all
the photons every time.
