Thanks, it worked!. But, it seems to have flipped the direction of the light.
It's either upside-down,backwards, or both. I chose a simple sphere with one
light just to test. But for a more complex scene it might help to know what
exactly did you change to make it so that there wouldn't be any triangles. What
did you do?
Also I found this article:
http://wiki.povray.org/content/Knowledgebase:The_Shadow_Line_Artifact
What do you think of it and the solutions?
