I have a simple particle system that is supposed to imitate rain. So I formed a simple raindrop and selected the raindrop for "Render as". But now I have the problem that the raindrops are not displayed in the finished render. They are only displayed in the viewport if I have selected "Viewport Display" -> Display as Point. With Display as Rendered, it is also not shown in the viewport. I just don't understand why .. I have attached a simplified file and would be very grateful if someone could take a quick look at it!

    $\begingroup$ it looks like it has to do with the Children > Interpolated option, I'm not sure how it is supposed to work? It doesn't seem to work from what I see... $\endgroup$

If you use Particles > Hair, you need to enable Render > Extra > Parent Particles to see the parents.

If you use Particles > Emitter, as it's the case here, Children > Interpolated doesn't seem to work (unless someone tells otherwise, I guess it's still here because you may want to switch from Hair to Emitter).
