Attaching Trapcode Particular to a Null
Picture this… a Super Hero is running extremely fast in a circle tying up villains around a pole…
1. I Would like to add a smoke trail on the ground that goes in a circle. Like his feet were catching the ground on fire or kicking up dust.
2. I will add a shape layer and make it rotate around the villains too – it will go so fast, so its just a blur.
So, I thought I could just add a 3d null and rotate it, and link the x,y,z of Particular to the Null. But I cant separate the dimensions in Particular.
Is there an easier way?
Something like this but not as elaborate: At 4:05 to 4:07

You’ll need three nulls.
Put one in the middle. This one will be spinning.
Put the other one as far outside as you need to get the size of circle you want. Parent it to the spinning one.
Apply the following expression to the third null:
c = thisComp.layer("child");(I think that’s right.)
c.toComp(c.anchor_point)
Replace the “child” part with the name of the parented null.
Then alt-click on the xy position of your Particular emitter.
Type [ then pickwhip to the x position of the third null.
Type comma then pickwip to the y position of the third null.
Type ]
Alt-click on the z position of your Particular emitter and pickwhip it to the z position of the third null.– The Great Szalam
