Editing the Direction of Sunlight

Rendering

Edit the direction of sunlight in a model as follows:

Select Rendering > Edit/Delete Lights. The Edit Lights dialog box opens.
Select the Distant Light row from the list.
Click the Edit Library button. The Distant Light dialog box opens.
Define the position and direction of distant light by moving the Rotation and Height sliders.
- Rotation is the direction of the incident sunlight. It can be adjusted 0 to 360 degrees around the model. If the value is 0, the direction of incidence is left. Larger values rotate the direction of incidence counter-clockwise.
- Height is the altitude angle of the light (the sun) (-90) 0 to 90. With a Height value = 0, the sun is to the level of the horizon. When the Height = 90, the sun is straight above. In Finland (Helsinki), the highest point the sun shines from is about 53.5 degrees at the summer solstice. In practice, lower altitude angles are more useful for rendering.
Confirm and close the dialog boxes by clicking OK.

You can create a distant light fixed in the viewing direction by adding a new light to the Shared folder in the library. The incidence angle of a distant light fixed in the viewing direction does not need to be edited when the viewing direction is changed.
