Forgot to say - do not use Fresnel with reflection. Fresnel is both reflection and refraction built into one node with a specific implicit rule that we can't change.

You can use it alone for realistic clear things, but not with the reflect or refract nodes because then you're fighting the fresnel node and doubling up, and not for colored things because the fresnel node doesn't do reflection color correctly,

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)
