Surface Settings Dialog Box

Use the Options > Element Attributes > Surfaces command to open this dialog box.
The Preview picture changes dynamically as you work in the Surfaces dialog box, so that you can see the effects of your settings. The Preview gives you an idea of what the chosen surface will look when rendered, depending on the rendering engine used.
Engine Settings: Choose a rendering engine from the list.
Important: All surfaces are specific to the engine for which they are set up. If you change a surface parameter for one engine, those modifications will not take effect for the same surface parameter if you switch to another engine.
