## Property Documentation

### allTestsPassOperation : Operation

Holds the stencil test operation for when depth and stencil test pass. Default is StencilOperationArguments.Keep.

Access functions:

Qt3DRender::QStencilOperationArguments::Operation | allTestsPassOperation() const

Notifier signal:

void | allTestsPassOperationChanged(Qt3DRender::QStencilOperationArguments::Operation stencilDepthPass)

### depthTestFailureOperation : Operation

Holds the stencil test operation for when the stencil test passes, but depth test fails. Default is StencilOperationArguments.Keep.

Access functions:

Qt3DRender::QStencilOperationArguments::Operation | depthTestFailureOperation() const
void | setDepthTestFailureOperation(Qt3DRender::QStencilOperationArguments::Operation operation)

Notifier signal:

void | depthTestFailureOperationChanged(Qt3DRender::QStencilOperationArguments::Operation depthFail)

### `[read-only]` faceMode : FaceMode

Holds the faces the arguments are applied to.

Access functions:
