# stencilAttachmentPixelFormat

The pixel format of the stencil attachment in the render pass the renderer encodes into.

## Declaration

```swift
var stencilAttachmentPixelFormat: MTLPixelFormat { get }
```

## Discussion

Discussion Relevant when the render pass uses a separate stencil attachment rather than a packed depth-stencil format. Use this format when compiling your own MTLRenderPipelineState objects for draw calls issued inside the render(using:_:) callback.
