Different Rendering Engines have different capabilities for displaying surfaces. Choose your intended Rendering Engine in the Surface Settings dialog box.
This way, only those controls will be available in Surface Settings that will actually affect the final rendered appearance.
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.
Commands are available to synchronize basic surface appearances between engines.
