Particles render in viewport, but not in final I have a super simple Particle system. I am instancing a sphere (Render->Object->DupliObject->Sphere) with a white emission material.
When I set the viewport to render everything shows up fine, when I hit F12 nothing shows....
WHY?

I don't have any postprocessing enabled in the rendersettings, and I tried to cache the particles, but nothing so far...
Any ideas?

Here is a simplified scene that shows that behaviour

I could create a new system in a fresh scene, and append it into my main scene. So the problem is not related to the rendersettings.
This is because the particle emitter is hidden in the render:



Particles inherit the object level properties of the emitter, so hiding the emitter object will hide the particles.

To exclude the emitter from the render without hiding the particles, disable Emitter in Particle settings > Render:



This is already disabled in your file.

To hide the emitter in the viewport without hiding particles, see Is it possible to hide particle emitters in the viewport without hiding particles?.
