Fade stars from starfield

When I create stars with the "Starfield" module with a very low speed some stars suddenly disappear, see the orange one here https://youtu.be/fj-aZ1ZAzIs?t=78

This happens only in the final render, not in the preview, and it's visually not very pleasing.

It would be nice (not only for this issue) to have the possibility to define a time for the Starfield-module after which a star (slowly-) fades away.

This test render was created using a modified version of Particles 2 from IteratorBasicExamples:

You will not see any stars popping on or off but it does have a bit of a pre-roll to get the first 'stars' to the edge of the screen. Also, there is occasional occlusion when a faster star passes in front of a slower star.

Popping off is eliminated by wrapping the motion in front of the screen. Popping on is disguised by a series of dark planes near the star's origin. As each star passes through each plane, it gets a little brighter.

An advantage of this setup is that stars can have different shapes and colours, rotations etc.

This looks even nicer than the Starfield-module, I have to try that.
Thanks a lot for the idea and the video :geek:
