## ComputeDetailInstanceTransforms(int, int, int, float, Bounds)

```csharp
public DetailInstanceTransform[] ComputeDetailInstanceTransforms(int patchX, int patchY, int layer, float density, out Bounds bounds)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The x index of the patch.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The y index of the patch.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The prototype index.**** (\[float]\(https\://learn.microsoft.com/dotnet/api/system.single)): The density setting of the detail.**** (\[Bounds]\(/engine/6000.3/script-reference/unityengine/bounds)): Returns the bounds of the detail objects.

### Returns
