Can't hide object which particles are based on, without losing particles 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.

Blender 2.7x

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.



Blender 2.8x

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.
