Particle effect on a sprite only?

Is it possible to show a particle effect only within the bounds of a 2D sprite?

For example: if I was to make a bubble gun I want particles to only show within the chamber of the gun. Right now the particles flow outside of the chamber of the gun onto everything else.

 

I would use a separate material for the chamber, and have a RenderTexture that provides a moving image of the bubble effect of your particle system.

Then you would put a separate camera to create that bubble texture from the particle system somewhere else far away or on a different layer. See attached for an example, or just google for RenderTexture setup examples.

@MousePods , @Kurt-Dekker Thanks for the replies I'll give these a look.
