What is one key feature of the Particle System that is not found in the VFX Graph?

The Particle System in Unity is designed to be a user-friendly tool that allows developers to create and manage particle effects quickly, making it accessible for various game development scenarios. One of the key features of the Particle System is its use of built-in shaders. These shaders are pre-configured materials that can be directly applied to particles, enabling users to instantly achieve visually appealing effects without the need for extensive knowledge of shader programming or custom shader creation. This streamlined approach significantly reduces the complexity involved in implementing particle effects, allowing designers to focus more on creativity rather than technical requirements.

On the other hand, the VFX Graph is a more advanced tool focused on high-performance visuals, offering a modular and node-based interface for creating particle systems. While it allows for sophisticated visual effects, it requires a deeper understanding of graphics programming and does not rely on built-in shaders in the same way the Particle System does. Instead, artists and developers are encouraged to create their custom shaders tailored to their specific needs, which may involve a steeper learning curve.

This distinction highlights why built-in shaders are a key feature of the Particle System that sets it apart from the VFX Graph.
