Adding Render Effects

In many cases, rendering a scene is only the start of the work to produce some final output. The post-pro-
duction process is often used to add lots of different effects, as you’ll see when I discuss the Video Post
interface. But just because you can add it in post-production doesn’t mean you have to add it in post-pro-
duction. Render effects let you apply certain effects as part of the rendering process.
You can set up all render effects from the Rendering Effects panel, which you open by choosing Rendering ➪
Effects. Figure 46.15 shows this dialog box.
The Effects pane displays all the effects that are included in the current scene. To add a new effect, click the
Add button to open the Add Effect dialog box, in which you can select from a default list of nine effects:
Hair and Fur, Lens Effects, Blur, Brightness and Contrast, Color Balance, Depth of Field, File Output, Film
Grain, and Motion Blur. You can delete an effect from the current list by selecting that effect and clicking
the Delete button.
Below the Effects pane is a Name field. You can type a new name for any effect in this field; doing so enables
you to use the same effect multiple times. The effects are applied in the order in which they are listed in the
Effects pane. To the right of the Effects pane are the Move Up and Move Down buttons, which you use to
reposition the effects in the list. The effects are added to the scene in the order that they are listed.

Caution
It is possible for one effect to cover another effect. Rearranging the order can help resolve this problem. n
The Merge button opens the Merge Effect dialog box, where you can select a separate Max file. If you select
a Max file and click Open, the Merge Rendering Effects dialog box presents you with a list of render effects
used in the opened Max file. You can then select and load any of these render effects into the current scene.
