OHHHH!!! THANK YOU!!!
I have been trying to figure out planet rings for over a year, every time I’d ask people just replied “UVmap”
(Never could figure out UV mapping)
your solution is VERY easy, and yeilds PERFECT results!!! thanks!
now, as for planetary glows, there are three ways to do them:
1: Huge halo at planets core
2: halo texture on extruded circle
(Those were posted above)
or a third, and my personall favorite.
add a circle will 100 vertexes at the center of the planet, scale it to the EXACT or SLIGHTLY smaller size then the planet.
give it a halo material, adjust halos to a good size, you MAY have to subdevide a few times if you ahve alarge planet.
now, get your scene setup, and rotate so the circle is facing the camera (Use only top, left, front views) render, now, delete vertexes on dark side of planet, and taper the ones near the light/dark area of the planet.
