# SetMatrixArray

> Set a matrix array property.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.6/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

## SetMatrixArray(string, List\<Matrix4x4>)

Set a matrix array property.

```csharp
public void SetMatrixArray(string name, List<Matrix4x4> values)
```

### Parameters

**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): The name of the property.**** (\[List\<Matrix4x4>]\(https\://learn.microsoft.com/dotnet/api/system.collections.generic.list-1)): The name ID of the property retrieved by [Shader.PropertyToID](/engine/6000.6/script-reference/unityengine/shader/propertytoid.md).

### Remarks

Adds a matrix array property to the block. If a matrix array property with the given name already exists, the old value is replaced.

The array length can't be changed once it has been added to the block. If you subsequently try to set a longer array into the same property, the length will be capped to the original length and the extra items you tried to assign will be ignored. If you set a shorter array than the original length, your values will be assigned but the original values will remain for the array elements beyond the length of your new shorter array.

## SetMatrixArray(int, List\<Matrix4x4>)

Set a matrix array property.

```csharp
public void SetMatrixArray(int nameID, List<Matrix4x4> values)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The array to set.**** (\[List\<Matrix4x4>]\(https\://learn.microsoft.com/dotnet/api/system.collections.generic.list-1)): The name ID of the property retrieved by [Shader.PropertyToID](/engine/6000.6/script-reference/unityengine/shader/propertytoid.md).

### Remarks

Adds a matrix array property to the block. If a matrix array property with the given name already exists, the old value is replaced.

The array length can't be changed once it has been added to the block.

If you set a shorter array than the original length, your values will be assigned but the original values will remain for the array elements beyond the length of your new shorter array.

```csharp
public void SetMatrixArray(string name, Matrix4x4[] values)
```

### Parameters

**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): The name of the property.**** (\[Matrix4x4\[]]\(/engine/6000.6/script-reference/unityengine/matrix4x4)): The name ID of the property retrieved by [Shader.PropertyToID](/engine/6000.6/script-reference/unityengine/shader/propertytoid.md).
