I found a video which I would love to recreate.
There are stars that form “clouds” which are interconnected somehow, still everything is random.
I played around with different noise functions, like perlin and cellular noise, but I can’t manage to spread the stars in a similar way like in the video.
Cool video.
I’m not sure but it looks like there are 2 effects going on there. There is a background starfield… and then in the foreground there are moving star clusters distributed with what looks like some kind of “noise” function.
The individual stars look like a sprite kinda like this:
Any idea how I can control, that the volumetric noise won’t be “cut off” once it reaches the borders of the sphere, but instead end with organic shapes there?
Hm. That’s more like artistic request. I mean, there might be many ways, but it is hard to guess which will work for you. So you have to explore various possibilities.
Here is one clustering from close distance and from far away, it is still somewhat globular, but that’s the default shape of things in the space:
