How to delete particles

[happtain]

Hello,
I would like to make a scene where an emitter continuously emits tens of thousands of particles, such as a fountain, but too many particles will increase the burden on the system. Is there any way to delete particles that leave the specified area during the simulation?

Best Regard.

You can define a bounding box for the emitter and when a particle is outside of this box it is reused (emitted again as new particle). See here:
