I created a scene in after effects using an idea from this commercial and wanted to know how to add particular in a large scene similar to the one where the orbs are flying over the ocean. I have the orbs and scene already built, I just need to add some particle lights throughout the scene. Also, if there is a way to add fog or atmosphere using trapcode into the scene as well for some extra spice help would be appreciated as well.
What are you using for the orbs? A light? If so, just make a comp sized solid and apply particular. Have it emit from the light and you are good. If not, just link a null, or light or anything to the orbs location and picwip the particular emitter to it to have the emitter follow the orbs. As for ambience in the scene, Particular would be a little overkill for fog. I have found that a large box emitter with small spheres as dust adds alot of atmosphere and depth to the scene.
