To clarify i'm not in this instance trying to hide emitter. The emitter oblong shape with arrow is supposed to be there. The particles are all based on a torus shape so all the little pink coins are based on that but i want to hide from render the large torus i have elsewhere on the screen. I un-clicked camera under ray visibility but then lost both the particles and the large torus. Thanks for any tips.
Select the large torus.
Press the M key and change the layer it lives on.
Then in render layers Shift-Select the layer you chose to remove that layer from being render.
Go to the Object Properties panel.
De-select Show in renders
To explain this, the properties you are changing ar only for the instance you selected, not any instances that are generated by the particle system.
