Rendering Particles

I’m working with particles for the first time and can’t seem to get them rendered.
I’ve got them going into a Geo and have set the render flag but they’re not showing up in the render node.
I can get a sphere SOP to render, but no particles!
Any help would be greatly appreciated!

One thing that may be happening is your particles are not colored/ or perhaps getting lit up enough to be showing up in your render. The background of your render may be your problem if your particles are starting out black. They may indeed be there, you just can’t see them.

Here’s an ultra basic render with some particles for you to glance at. 3 renders; One uses a Geo, one render uses a SOP , and a third shows both at the same time. Both sets of particles are coloured with the Constant MAT, the most basic of 3D materials. You will want to set up geo comps for each material or color in a scene.

If this doesn’t answer your question you should upload an example file of where you are having trouble.
