QUESTION

When I take a camera view of the exterior of my house, the shading is on the wrong side. How can I adjust the sunlight to come from the right direction?




ANSWER

If you create an exterior 3D view, the program creates a Default Sun Light source. It's easy to adjust the various aspects of this Default Sun Light to properly reflect different times of day using the Default Sun Light Specification dialog while a 3D view of your plan is open. The key to getting the sunlight effect you want is to adjust both the tilt angle, and direction angle.


To adjust the default sun light

  1. Take a Camera  view of the exterior of the structure and then select 3D> Edit Active Camera .


  2. In the Camera Specification dialog that opens, check the Show Shadows box and then hit OK to confirm the change and close out of the dialog.


  3. With shadows now displaying in the view, select 3D> Lighting> Adjust Sunlight to display the Adjust Sunlight dialog.



    • Use the Intensity drop-down option to control how bright the default sun light displays in 3D views.

    • If you don't want the sun to follow the camera, uncheck the Sun Follows Camera box and proceed to specify your own tilt and direction angle.

    • Change the Tilt Angle to specify the angle of the sun light with respect to the horizon. A value of 90 degrees means that the light is pointing straight up, whereas a value of -90 degrees means that the light is pointing straight down. 0 degrees is parallel to the horizon.

    • Set the Direction Angle to specify the direction that the sun light points toward. 0 degrees is measured horizontally on screen, pointing to the right. Positive values will then rotate in a counter-clockwise direction, while negative values rotate clockwise.

    • Click in the Color rectangle to define the color of the light being modeled. The color white has the least effect on material colors and textures.


  4. Click OK to apply your changes and see the results update in your open 3D view.





In Home Designer Pro, you have more control over how the programs sun displays by utilizing the Sun Angle Specification dialog, where you can give the program your latitude and longitude, along with the date and time, and the program will then automatically set the correct Sun Angle for you.
