# parameterHandle(name:)

Returns a handle for the parameter with the given name.

## Declaration

```swift
static func parameterHandle(name: String) -> MaterialParameters.Handle
```

## Parameters

- `name`: The name of the parameter as declared in the shader graph.

## Discussion

Discussion Handles provide a faster path for repeated parameter access compared to name-based lookups. Obtain a handle once and reuse it across frames.
