# accelerationStructureBuildFlagsOverride

> Whether to override the build flags specified when creating a RayTracingAccelerationStructure.

## Definition

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

```csharp
public bool accelerationStructureBuildFlagsOverride { readonly get; set; }
```

### Remarks

If you set this value to `true`, Unity uses [RayTracingMultiGeometryInstanceConfig.accelerationStructureBuildFlags](/engine/6000.5/script-reference/unityengine/rendering/raytracingmultigeometryinstanceconfig/accelerationstructurebuildflags.md) when it builds the acceleration structure for the geometries referenced by the ray tracing instances specified using this configuration.
