Which module in the Particle System controls the rate of particles produced every second?

The Emission module in the Particle System is specifically designed to control the rate at which particles are generated within a given time frame, typically expressed in particles per second. This module allows artists and developers to specify how many particles should be emitted over time, which is fundamental in creating the desired effects such as smoke, fire, or explosions.

When using the Emission module, you can adjust the "Rate over Time" value, which determines how many particles are produced during each second of the effect's lifespan. This control is essential for achieving the right visual impact and ensuring that the particle system responds dynamically to different gameplay situations or aesthetic requirements.

Understanding the role of the Emission module is crucial for effectively utilizing the Particle System in Unity, as it directly influences how dense or sparse the particle output appears in the game scene. Other modules, such as Lifetime, Shape, and Velocity, serve different purposes, such as determining how long particles last, the shape and volume from which they are emitted, and their initial movement speed, respectively. However, they do not control the emission rate of particles directly.
