# GpuBvhBuildQuality

> BVH build quality.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEditor.Embree](/engine/6000.7/script-reference/unityeditor/embree.md)
* **Assembly:** UnityEditor

```csharp
public enum GpuBvhBuildQuality
```

## Remarks

The quality levels represent a trade-off between acceleration structure build performance and ray tracing performance. The slower the acceleration structure build speed, the higher the runtime ray tracing performance is.

## Fields

| Value                                                                                     | Description                                                                                                        |
| ----------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------ |
| [High](/engine/6000.7/script-reference/unityeditor/embree/gpubvhbuildquality/high.md)     | Highest possible ray tracing performance, slowest build time. This quality level uses spatial splits when enabled. |
| [Low](/engine/6000.7/script-reference/unityeditor/embree/gpubvhbuildquality/low.md)       | Faster build time, slower ray tracing performance. Can be beneficial for dynamic scenes.                           |
| [Medium](/engine/6000.7/script-reference/unityeditor/embree/gpubvhbuildquality/medium.md) | This level balances the build time and ray tracing performance.                                                    |
