Meanwhile, check this out. It's an illustration I have wanted to make for a long time.

I shrank my EnvSphere down to Scale 1.2% and then I modified the shader to "burn" a hole in it, so we can see both inside and outside. It took nine nodes to make this effect, including the outside glowing darker than the inside. For those of you that are a bit more advanced, can you figure out how to do this?

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)
