Here's the second render. In this one, I turned off my sky sphere in ray tracing. Then I connected a blurred copy of the scene to the shader.

This render took 30 seconds. The reflections aren't the same, as a Sky_Sphere does not quite do all the math the same as real ray-traced reflections, but it's ok.

There are some polygons that didn't render correctly - this is a standard problem having to do with Bias settings. Ignore that.

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)
