black glass when UVsphere is split in two

[scatman]

Why is indigo rendering a black line where the 2 halves of the UVsphere meet? All of my normals are out...what gives. I wish it ware easier to post an image in a forum, but I shouldn't be complaining. Please see the attached images (if I attached them correctly)

it looks to me like its the flat surface of your red glass semi-sphere. It looks black but i think its actually dark red, and that would be due to the high color absorption of your material (or so i think anyway).

i dont think indigo's behaviour is wrong in this case.

Thanks for your response. I reduced the absorption (GAIN) setting in the Indigo GUI from "10" to "5", but the blackness persists. Did I adjust the wrong setting?
