Chapter 20: Using Lights and Basic Lighting Techniques

If the General Settings option is selected, then a separate rollout opens with all the typical settings, includ-
ing Multiplier, Color, Shadows, Map Size, and so on. You can apply these changes to the Selected Lights or
to All Lights. The Light Lister provides an easy way to change the parameters of many lights at once.
If either the All Lights option or the Selected Lights option is selected, then the parameters are listed in the
Lights rollout. Using this rollout, you can change the settings for any of the listed lights that affect all lights.
The Refresh button updates the Light Lister dialog box if a new light has been added to the scene or if any
parameters have been altered in the Modify panel.

Note
If several lights are instanced, then only one of the instanced lights appears in the Light Lister dialog box, but each
of the instanced lights can be selected from a drop-down list. n

Placing highlights
The Place Highlight feature enables you to control the position and orientation of a light in order to achieve
a highlight in a precise location. To use this feature, you must select a light object in the scene and then
choose Tools ➪ Align ➪ Place Highlight, or click the Place Highlight flyout button on the toolbar. The cursor
changes to the Place Highlight icon. Click a point on the object in the scene where you want the highlight
to be positioned, and the selected light repositions itself to create a specular highlight at the exact location
where you clicked. The light’s position is determined by the Angle of Incidence between the highlight point
and the light.

Tip
If you click and drag on the object surface, then a small blue vector points from the surface of the object. The
light is positioned inline with this vector when the mouse button is released. This is helpful when trying to pre-
cisely place a light. n

Tutorial: Lighting the snowman’s face
You can use the Place Highlight feature to position a light for our snowman. To place a highlight, follow
these steps:

1. Open the Snowman.max file from the Chap 20 directory on the DVD.
This file contains a simple snowman created using primitive objects.
2. Select the Create ➪ Lights ➪ Standard Lights ➪ Target Spotlight menu command, and position the
spot light below and to the left of the Snowman model.
3. To place the highlight so it shows the Snowman’s face, select the spot light and then choose
Tools ➪ Align ➪ Place Highlight. Then click and drag on the Snowman’s face where the highlight
should be located, just above his right eye.
Figure 20.6 shows the results.
