```csharp
using UnityEngine;

public class Example : MonoBehaviour
{
    // Checks if the texture mipmap limit group "MyGroup" exists in the project and prints a message to the Unity Console.
    void Start()
    {
        const string textureMipmapLimitGroupName = "MyGroup";
        bool myGroupExists = TextureMipmapLimitGroups.HasGroup(textureMipmapLimitGroupName);
        Debug.Log($"Texture mipmap limit group '{textureMipmapLimitGroupName}' {(myGroupExists ? "exists" : "does not exist")} in this project.");
    }
}
```
