PS, please remember that the nature of the Vortex field is to
PULL an object in a circular or spiraling direction.

So, by that nature, depending on other fields, shapes or object settings, most often your particles WILL get PULLED in upon themselves first, before other objects, fields, etc. take over.

The trick to pulling off this illusion, is to find that "happy" medium of Vortex attenuation, to emitter conserve ratio that gives your galaxies that beautifull spin..... on life
