I dont know if this needs to be in design or building, but here it is. I wanted to make a black hole but with smooth outlining, I made a black neon sphere and added an attachment in there with a black circle particle effect inside, its stationary and doesnt move.
Allthough when you move your camera for some reason this particle effect goes outside of the neon sphere and this gives away that these are 2 circles, why?
No, but this is because the particle isn’t visible through the black hole and “over” other particles otherwise. (Also setting it to 0 doesn’t change this)
I did this in a hurry, but the idea is you put a black sphere in the middle, then you have several MeshParts with their normals inverted surrounding it (using a variety of colours):
Open Blender, create a new file (just close the popup) then type xdAmu, press tab, alt-right click the equator of the sphere then type oO7sZ and adjust with mouse and scroll wheel then click or press enter to get a similar mesh. Type a, alt-n, f to flip normals. If you want smooth shading too, type ctrl-f, h.
Some things may difference on your blender version, it should be pretty easy to find things out, I suggest also smoothing out the outer edge of the black hole ring.
