Thanks for the awesome help on making my particles orbit, but now I have another.
When I Gaussian blur to the emitter, the particles come back in front of the layer, what I don't want. When I take of the Gaussian (or any blur), it goes back to the behind the middle object. How do I blur my emitter and keep it in the back of my layer, coming back around into the front (true 3D as in an orbit). Thanks
Anything that causes a layer to rasterize will effectively flatten you 3D layer into a 2D layer. You can add blur to the particle that the emitter is using; all the particles in the emitter will get blurred then.
