    Part 7B. Barrier Fence

    1. We can’t have a highway just end without warning, so let’s add one. We’ll use a Wall, another useful VNS feature in the 3D Object Task Mode. Right-click the Walls category and Add Component of this type. We’ll use an existing vector to control it.

    A software interface showing a dropdown menu with options related to 3D materials, including adding components of a selected type. An arrow cursor is pointing to "Add Component of this type.

    2. Name it End of the Road. Expand the Walls category in the Scene-at-a-Glance.

    A screenshot of a Wall Editor settings window titled "End of the Road", showing options for enabling panels, setting heights relative to vector elevation, and vector placement details.

    3. Copy the Dead End vector from the lower S@G tab to End of the Road Wall.

    4. Make the Height Relative to Ground Elevation. Increase Panel Top Height to 3 meters.

    5. Go to the Panels page and create a Diffuse Color Texture.

    6. Choose Stripes from the Selected Element dropdown list. View From the South-Y.

    7. In the Colors section, change the left pin color to white.

    8. Change the right pin color to red.

    9. Go to the Size & Position section and open the Rotation tab. Change the Y axis value to 45° to complete the warning barrier texture. Close the Texture Editor.

    10. Save the project and render a preview. The barrier is mostly hidden because it’s resting on the ground beyond the highway. This will fix itself when we raise a pad for the development. We can’t see the barrier texture because the Wall is lit from behind.

    A road abruptly ends with a red and white striped barricade, with a forested area visible in the background.

    11. Go to the Wall Editor Panels page and Show Advanced Features

    12. Increase the Luminosity to 50%. This is not a magical number. Like many VNS values, it depends on the scene and lighting and is the result of trial and error.

    Screenshot of a Wall Editor software interface displaying options for adjusting panel material properties, including diffuse color, luminosity, transparency, specularity, reflectivity, and bump intensity.

    13. Save the project and render a preview.

    14. This is a simple application of a very powerful tool. For a look at using Walls to raise city buildings, explore the NYC project in the Demos folder.
