[VFX Graph] - Bound particles to a volume

Unity Engine

Is it possible to bound particles to a volume in the VFX Graph?
I’m trying to create a particle system that only operates inside this Cone Position/Volume.

I want the particles to spawn at the volume bounds and it’s depth all around the volume. The spawning part I got working but I also have an Issue. A lot of the particle tends to spawn at the origin of the volume and bundle there (Where the line spans the radius)

Is there a way to prevent this from happening? Maybe I went about creating this the wrong way?

You need to use thickness parameter in the Cone Position so that it spawns only on the bounds bounds.

You could use negative directional velocity in the Update to make particles go inwards rather than outwards.
