Oops! Too Late! Rendered. Here's the Render with IDL only in the GI Zone, with the Zone set to a darker gray color.

I'll follow the above directions, and render again.

Forgot? I guess I didn't fully understand. I thought I had done that. Oh, well, my bad. Perhaps I'll learn. Thanks for being patient with  me.

OK, we'll see what the next render looks like.

By the way, I don't like the washed-out look of IDL only (as I mentioned above).
