I tried to place a teapot orbiting a Mars (Russel's Teapot!
) I had created, orbiting the Sun in the A Sun system.
When I zoomed in, Mars got dark (shaded) everywhere instead of the original place, and the Sun looked like it's shape conflicted with the glow. I'll try to recreate the problem and upload some screenshots.
I managed to get this so far, but it isn't very easy to see on it. The star has some lines, but some of the areas between flicker and look like the glow is removed.
I didn't place any teapot in this simulation. But the sun-flicker-thing only happens when I go close to Mars, as soon as I zoom out it disappears again.
