Click Quick Render
.
 |
Step 1 - No light
source |
In our example, we are going to create a light
source that matches the lighting of the environment pictures, i.e.
the sun light. |
-
Click Directional Light
then click Quick Render
again to check the result.
 |
Step 2 - One
directional light source |
As you can see above, the result is
better but still not realistic enough.
Note: if
there is not shadow cast on the pavement, edit the Bottom wall
properties then select the On check box in the
Lighting tab. |
-
Modify the light orientation using the green
manipulators so that the red car shadow matches the shadows of the cars
parked behind. For our example, a correct position would be:
Changing the viewpoint may be helpful to position
the light (for example you can use the Top or Left view). |
-
Double-click the camera to go back to the
original viewpoint then click Quick Render
.
 |
When using spot or point lights, pay attention to the lighting end
in order to make sure that the light cone includes the object and
thus, correctly illuminates it. Otherwise, the object will be too
dark.
For more information on light sources, refer to
Defining a Light Source in this
guide. |
-
For a more realistic lighting, you may need to create
soften shadows. To do so, simply duplicate the original light (Copy
> Paste), slightly modify the orientation of the new lights then
decrease the intensity (only one light cast shadows) as shown in step 6:
-
Access the
Lighting tab in the Properties dialog box to soften the
light and give it a faint yellow color.
 |
Intensity
parameters: Red= 173, Green= 173, Blue= 167 |
Do not forget to select the Ray Traced
check box to activate shadows. |
-
Edit the Lighting parameters of the
duplicated light (intensity parameters: R=G=B= 80) then select the
Enable check box in the Shadows tab before creating a
quick render.
You can click Stop to
interrupt the process as soon as an unsatisfactory result is
detected.
When using a spot or point light, changing the attenuation may
also make the lighting more realistic. |
-
When satisfied, click Create a Shooting
then render this shooting to check the result:
 |
Shooting rendered from current
viewpoint |
 |
Shooting rendered from camera
viewpoint |
 |
Remember that the
more light sources, the more difficult the tuning of the scene's
global illumination. |
