# GraphicsStateCollection

> Collection of shader variants and associated graphics states.

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine.Experimental.Rendering](/engine/6000.0/script-reference/unityengine/experimental/rendering.md)
* **Assembly:** UnityEngine.CoreModule
* **Inherits from:** [Object](/engine/6000.0/script-reference/unityengine/object.md)

```csharp
public sealed class GraphicsStateCollection : Object
```

## Remarks

Use graphics state collections to record shader variants and graphics states encountered at runtime and prewarm shader variants.

Each shader variant in the collection may have one or more associated graphics states. Each permutation of a shader variant and a graphics state will result in a single GPU representation of the shader being created by Unity.

## Examples

```csharp
using UnityEngine;
using UnityEngine.Experimental.Rendering;

public class GraphicsStateCollectionTracing : MonoBehaviour
{
    public GraphicsStateCollection graphicsStateCollection;

    void Start()
    {
        graphicsStateCollection = new GraphicsStateCollection();
        graphicsStateCollection.BeginTrace();
    }

    void OnDestroy()
    {
        graphicsStateCollection.EndTrace();
    }
}
```
