Blender Geometry Nodes Starfield & Motion Lines

These are two geometry node setups to scatter stars or lines on a sphere or half-sphere geometry. Both are light, fully procedural (no mesh) and can be transformed and animated in many ways. No simulation though. 

I have been using those stars many times for space and sci-fi illustrations. It can be used to achieve FX (like star wars light-speed effect)as well.

It comes with 3 procedural shaders: Stars, Lines, World.  

Version:

Blender version is 3.6.4. 

This setup version is 1.1, updated

What's new:

- new groups, enhanced presentation and performance.

- geometric culling feature on both. It will delete points outside the camera field.

- control object to ease orientation and scale of motion lines.

Quick example scene is included.
