Spawning new particles during simulation

[finn777-yea]

Hey, I am currently working with warp to simulate industrial painting scenarios, where I need some guidance on spawning particles dynamically during the simulation, in order to model the behavior of a spray emittor.

Checked most of the example cases, where the number of the particles is set when inititialized. I wonder if there is a proper way of spawning new particles in each step during the simulation.

Any insights would be highly appreciated :)
