# System Seed Menu Path : **Operator > BuiltIn > System Seed** The **System Seed** Operator outputs the internal Visual Effect system seed. The Visual Effect Graph uses this value to initialize a random number generator per component. The system seed is generally constant but it can regenerate, if you enable **Reseed on Play** in the Visual Effect component, when a new play event triggers. ## Operator properties | **Output** | **Type** | **Description** | | -------------- | -------- | ------------------------ | | **systemSeed** | uint | The current system seed. |
