Using Render Layers

Use Render Layers to define how single geometries should be rendered and displayed. This feature is only available in Raytracing mode. The procedure described here uses a car and its accompanying geometries as an example.

1. Ensure raytracing is enabled (Visualization > Toggle Raytracing).

2. Select Rendering > Render Layer.

3. Right-click within the Render Layer dialog box and select Create Layer.

4. Double-click the new render layer to rename it; for example, "Car."

5. Select Scene > Scenegraph.

6. Drag geometry from the Scene Graph onto the new layer; for example, in this case, you could drag the geometry of the car onto the Car layer you created.

7. Follow the same steps to create another layer named "Wheels" containing geometry for the wheels.

8. Double-click inside the columns of the Render Layer dialog box to disable or enable different levels of visibility for the geometry in each layer.

   For example, you could turn PrimaryVisibility off for the car, and the geometry of the car will not be visible, but its other effects will be, such as shadows.

9. Click (Activate Layer) to see the results of your selections.
