Not sure what happened to my answer that I typed out, but here's the short(er) version. I'm also not sure if this (or another forum) is where I'm supposed to edit the title and add "Solved" to it, but if it is, I can't remember how to do that.)
First, the previous question got me wondering if the different type mesh might be the issue. It was. I don't know what the difference is, but the normal mesh worked.
Just FWIW, the planet i'm creating is Epsilon Eridani (Eri) 4, home to a colony of over 200,000 human men, women, and children. The planet is attacked by a missile fired from behind the camera. It then rapidly goes from its blue-green to grey and rapidly to a brilliant white....and then rapidly fades into nothing, leaving only stars in the background.
That's the intro to my game (a FPS). The working title is:
"Epsilon Eri 4: Mission: Payback"
While in the shower one day, the entire game (from the intro to the player getting an intelligence report to both total victory and side-missions which, failing to reach total victory, give at least partial victory) played out in a flash across my brain.
