# MipmapLimitDescriptor(bool, string)

> Creates a new MipmapLimitDescriptor.

## Definition

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

```csharp
public MipmapLimitDescriptor(bool useMipmapLimit, string groupName)
```

### Parameters

**** (\[bool]\(https\://learn.microsoft.com/dotnet/api/system.boolean)): Enable or disable mipmap limit effects for a Texture.**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): The [TextureMipmapLimitGroup](/engine/6000.5/script-reference/unityengine/texturemipmaplimitgroups.md) to use the mipmap limit of.

### Remarks

Use a `MipmapLimitDescriptor` to determine whether a texture uses a mipmap limit when you create the texture using a constructor.

If you create a texture using a script, the texture doesn't use mipmap limits by default. The texture uses the mipmap limit of `groupName` if you set `useMipmapLimit` to `true`. If the group is not defined (either `null` or an empty string), the texture falls back to following the global mipmap limit.

The texture also uses the global mipmap limit if the group is not known by the Editor.
