I got yafray yesterday and, after getting so annoyed at yable for giving me black images, I started to mahe a couple of spheres.
IT WORKED!!
then a simple glass material etc.
I was quite pleased with the outcome, but I would like to get rid of those fake gleams and make it look like the light was coming through a window (four white squares).
Can I make these emt light, or should I make some white planes and make then shadeless?
How would I go about this?

Thanks
Ian

nice, but there’s no refraction ?

There is refraction!
There is little reflection, so I am going to increase it.
