6. The wood looks much better now, so let's move on to the brightness of the scene.
Open the Render Settings window, and go into the Indirect Lighting tab. Click the
Input arrow next to the Physical Sun and Sky attribute's button (Figure 10.43). Doing
so opens the Attribute Editor for the Physical Sun and Sky.
7. Set Multiplier to 0.5 from 1.0, and re-render the frame. The brightness comes down
nicely, and the wagon is less blown out than your previous renders. See Figure 10.44.

8. Let's play with the direction of the Sun. Look in your persp panel, and you see a
Directional light sitting smack in the middle of the scene. Maya uses this light to
set the direction of the sunlight, and it doesn't contribute to the lighting of the
scene in any other way. Only its rotation is important to PSAS. Its intensity, color,
and other attributes are irrelevant. In this scene, the Directional light is called sun-
Direction and is in the wagon behind the third texture placement node, as you can
see in Figure 10.45. The light is currently pointing sunlight almost straight down,
as if the Sun is high in the sky. It seems as if it's about noon. RotateY for the sunDi-
rection light is -75.
