# RenderStateBlock

> A set of values that Unity uses to override the GPU's render state.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine.Rendering](/engine/6000.7/script-reference/unityengine/rendering.md)
* **Assembly:** UnityEngine.CoreModule
* **Implements:** [IEquatable\<RenderStateBlock>](https://learn.microsoft.com/dotnet/api/system.iequatable-1)

```csharp
public struct RenderStateBlock : IEquatable<RenderStateBlock>
```

## Remarks

When you call [ScriptableRenderContext.DrawRenderers](/engine/6000.7/script-reference/unityengine/rendering/scriptablerendercontext/drawrenderers.md), you can use this to override the render state for some or all of the geometry.

**Note:** You must set [RenderStateBlock.mask](/engine/6000.7/script-reference/unityengine/rendering/renderstateblock/mask.md) to tell Unity which parts of the render state to override to apply. For example, to apply the values in [RenderStateBlock.blendState](/engine/6000.7/script-reference/unityengine/rendering/renderstateblock/blendstate.md), [RenderStateBlock.mask](/engine/6000.7/script-reference/unityengine/rendering/renderstateblock/mask.md) must include [RenderStateMask.Blend](/engine/6000.7/script-reference/unityengine/rendering/renderstatemask/blend.md).

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

public class OverrideRenderStateExample
{
    ScriptableRenderContext scriptableRenderContext;

    // Placeholder data
    DrawingSettings exampleDrawingSettings;
    CullingResults exampleCullingResults = new CullingResults();
    FilteringSettings exampleFilteringSettings = new FilteringSettings();

    public void OverrideRenderState()
    {
        // Tell Unity how to override the render state when it draws the geometry.
        var stateBlock = new RenderStateBlock(RenderStateMask.Depth);
        stateBlock.depthState = new DepthState(true, CompareFunction.LessEqual);

        // Schedule the drawing operation.
        scriptableRenderContext.DrawRenderers(exampleCullingResults, ref exampleDrawingSettings, ref exampleFilteringSettings, ref stateBlock);

        // Perform all scheduled tasks, in the order that they were scheduled.
        scriptableRenderContext.Submit();
    }
}
```
