Short description of error
children particles do not show up
even if i turn them to 1000 children... noting happens
looks like they dont even get calculated
in hair mode it works - but in emission mode it dont
Exact steps for others to reproduce the error
make default particle system on default cube
go to children an turn it on

this is important for blender 2.90 release, we all need children particles working please :)
this needs to be high prio!

They are working with
ObjectorCollectionas render type, see:#80197.blend
It is just that
Halo,LineandPathare not being drawn/rendered by Eevee nor Cycles with emitter particles.@brecht, @JacquesLucke: there was already the discussion in #65542 (Particle trails not working) about removing these (and this was more or less approved) should we just make a TODO task for this?
This could be marked as a known issue.
But really solving this should be quite simple, so maybe you are @JacquesLucke can just make a patch to remove these options?

3.5 was realesed, still not working
This wont be rendering these types (also not in the future), better use geometry nodes for this (or set render_type to object and make appropriate objects), sorry.
Will put on my desk to remove for good...
I would like there was also an option to render particles just as "sprites" (single polygon always oriented to camera) without any geometry nodes magic etc.
Maybe it should be added like an "polygon" render option in particle system, simple and obvious.
Also it will be cool to have an option to render particles trajectories like curves, but it looks more complicated to implement
These have been removed now in
fbd2bd8154(so will be gone in 4.0).Would really suggest using geometry nodes now, have a look around, I would assume there are already premade nodegroups out in the wild that achieve what you are after. Trails for example can be done like this https://www.youtube.com/watch?v=gOK4S5DWgUE
So after all this time, will close this report.
I think that will continue to disturb people.
What users see in Viewport is still absent, by default, of a render.
Workbench and Cycles are able to render geometry nodes points.
That would make sense to have a visualisation to render old particles as geometry nodes points with those engines, until there is a bundle of nodegroups replacing old particles.
