# GetMatrix

> Get a named matrix value from the shader.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.5/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

## GetMatrix(string)

Get a named matrix value from the shader.

```csharp
public Matrix4x4 GetMatrix(string name)
```

### Parameters

**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): The name of the property.

### Returns

| Type                                                                  | Description |
| --------------------------------------------------------------------- | ----------- |
| [Matrix4x4](/engine/6000.5/script-reference/unityengine/matrix4x4.md) |             |

### Remarks

This is mostly used with custom shaders that need extra matrix parameters. Matrix parameters are not exposed in the material inspector, but can be set and queried with `SetMatrix` and `GetMatrix` from scripts.

## GetMatrix(int)

Get a named matrix value from the shader.

```csharp
public Matrix4x4 GetMatrix(int nameID)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The name ID of the property retrieved by [Shader.PropertyToID](/engine/6000.5/script-reference/unityengine/shader/propertytoid.md).

### Returns

| Type                                                                  | Description |
