Animating in a perfect circle

[Phil]

draw a mask on one layer.

then copy the position of that mask *make sure you click on MASK SHAPE*
then past it in the emitter position value. i just tried it with particular, and it works like a charm :).

also, if you want it to repeat, use the “loop out” expression on the emitter position value.

one of the easiest and most flexible ways is to just parent it to a null. Then move your emitter away from the null to whatever distance you want your radius to be. Then simply animate the rotation of the null. The null acts as the Sun and your layer now revolves as if the Earth. It’s flexible because at anytime you can just reposition the Earth and it will revolve from there. Plus you can add different rotation offsets to the null(sun) to change the orbit.
