# VertexChannelCompressionFlags

> Use these enum flags to specify which elements of a vertex to compress.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEditor](/engine/6000.6/script-reference/unityeditor.md)
* **Assembly:** UnityEditor.CoreModule

```csharp
[Flags]
public enum VertexChannelCompressionFlags
```

## Remarks

Default settings: Position and TexCoord1 are uncompressed because high precision is usually desired. Everything else is compressed to save memory and conserve bandwidth.
