What happens to the Particle System when the maximum number of modules is reached?

When the maximum number of modules in a Particle System is reached, no new modules can be added. This limit is defined by the design of the Unity Particle System to ensure it operates efficiently and effectively within the constraints of performance and memory usage.

Each module in a Particle System is responsible for a specific aspect of the particle behavior or appearance, such as color, size, or shape. Once the maximum number of these modules is attained, the system cannot accommodate additional modules, preventing modifications that could potentially overload the system or degrade performance.

This limitation encourages artists and developers to use and manage their resources wisely, ensuring they choose only the most relevant modules for their particular needs within the Particle System. This design avoids complications that could arise from having too many layers of complexity, which can hinder performance and may lead to a convoluted setup that is difficult to manage.

Therefore, when reaching this limit, the correct behavior is to prevent the addition of new modules, ensuring the Particle System remains stable and performs optimally.
