## SetBufferData(ComputeBuffer, Array)

Adds a command to set the buffer with values from an array.

```csharp
public void SetBufferData(ComputeBuffer buffer, Array data)
```

### Parameters

**** (\[ComputeBuffer]\(/engine/6000.0/script-reference/unityengine/computebuffer)): The destination buffer.**** (\[Array]\(https\://learn.microsoft.com/dotnet/api/system.array)): Array of values to fill the buffer.
