Edit: screenshot and file below

Update: torus (the emitter) particles show up just if I convert the cone (the other emitter) in the modifier tab {which automatically converts also the torus}.

.blend file

enter image description here

I have a sphere and I applied to it hair particle system with two emitters:

  • one is a cone with material, no problem at all;
  • the other one is a torus, which got hair particles as well. Particles show up around the torus until I change it to render as object. After that, particles disappear from the emitter, even if the torus still has them.

Anyone who knows why?

With the cone converted:

It’s cycles.


  • $\begingroup$ show us your blend file - screenshot are better than nothing, but .blend file is the best way that we can help you $\endgroup$

if you choose "render as object" -> and choose "cube" as object, your hairs will be shown as that object, as cube. So it works as it should be.

Blender 2.91 result for me: enter image description here

  • $\begingroup$ If I do it it shows just cubes, not the torus with cubes on it $\endgroup$ Feb 16 at 11:42
  • $\begingroup$ is this the result you expect? $\endgroup$

  • $\begingroup$ Unfortunately not, there isn’t any issue with the torus particles themselves, but they disappear when you render the torus as object aka as the emitter for the sphere. At the point you will see the torus but not its particles (the cubes). I updated the question and added a new screenshot if you want to look at it. Cheers! $\endgroup$ Feb 16 at 13:23
