Why won't this particle system render? When I render my image, my particles system won't render, instead it just shows a black background.



I have search for answers and followed them.


I made sure that the render icon was on
I unchecked the emitter box that is in the "particles system" tab
I made a vertex group
I also added a mask modifier 


I just have no idea what to do for my particles to render.
I think I found your problem. Your compositing node setup looks like this:

You need to switch the node paths going into the Alpha Over node on the left so that it looks like this

I think that will solve your problem! Before you were layering the black background over the blue particles but if you switch them like in the second picture, the blue particles are going over the background!
