Quote - Because you don't have enough bounces set in your render settings to be able to do raytracing all the way through.

You need two bounces or more - one to enter the ball, one to exit.

Render settings are just as mysterious if you don't know what they do.

PS - Some people forget to enable raytracing, too. I used to write that in every post - enable raytracing, two or more bounces.

Arrrrghhh!!!

Of course you are right. LOL.

Thank you.
