Hmmm. Not sure what to say. But go check this post in the node cult. This is a new technique that works great for the two-sided detection.

I suspect that we did not turn on normals forward in the GC diffuse node. That's why it would behave differently.

But - given what we just learned in the linked thread, we have a new and better way to do the detection!

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
