You can now layer a Horizontal/Vertical (zebra stripes) or Curvature shader on top of any other diagnostic shader.
- Choose ObjectDisplay > Diagnostic Shading if the Diagnostic Shading window is not already open. (By default it is attached to the Control Panel).
- Select the objects you want to shade. (If nothing is selected all objects are shaded.)
- Select a diagnostic shader.
The objects display the shader.
- Select a second shader from the Layer pull-down.
The parameters of the layered shader appear below the parameters of the original shader in the control window.
The objects display both shaders.

- Choose None from the Layer pull-down to remove the layered shader.
Note: You cannot layer a Curvature shader over another Curvature shader.
