You can remove some lighting effects for a selected surface by converting surfaces to a wireframe depiction of the surface. When Wireframe is enabled, specular values and any applied textures are replaced with a wireframe view of the surface. When used on an image, the surface will adopt a screen-like look.

To convert to wireframe:

1. In the scene, select the surface to convert to wireframe.
2. In the Surface menu, enable Wireframe.

   
   

   The selected surface becomes a wireframe surface.
