Distant Light Fixed in the Viewing Direction

The distant light fixed in the viewing direction is intended to reduce completely black surfaces in visualization. You can create a distant light fixed in the viewing direction in your own library. If you add a distant light fixed in the viewing direction, the model's surfaces will appear lighter instead of dark (black) from the viewing direction.

In the example figure on the left, a distant light with an incoming direction from the front of the building and intensity of 0.8 is on in the model. On the right, a distant light fixed in the viewing direction with an intensity of 0.4 is also on.

Create a distant light fixed in the viewing direction in your own library as follows:

1. Select System | Rendering Textures > Lights. The browser is opened.
2. Select My Library.
3. Select a folder in which to save the light, or create a new folder, if necessary.
4. Move the cursor to an empty area in the right browser frame (thumbnail area).
5. Right-click to open the function menu, and select New Light.
6. Name the new light in the Create Light dialog box.
7. Select Distant as the light type.
8. Select the Location property, enter (0,0,0) in the field and click the Set button.
9. Select the To property, enter (0,0,0) in the field and click the Set button.
10. Confirm the data.
