Radial particle emitter

Lou I am trying to create a particle emitter that will start near the middle go out to a fixed distance and rotate sort of like a shield.

Anyone have any experience of if this is possible.

So in a sphere the sprites spawn moving outward rotating but at distance stop moving outward but continue rotating

An orbit module.
You can use the orbit to make your particles come out of the center and grow while rotating around the center. Just need to animate the offset for what you’ve described.
