Collecting Parameters

To help in organizing the various parameters that you use to animate a scene, you can use the Parameter
Collector to gather all custom and animated parameters used in the scene. The Parameter Editor can be
used to create custom attributes and parameters, but the custom attributes are attached to the specific
object or element that was selected when the attribute was created. This can make finding the custom attri-
butes difficult, but Max includes another tool that you can use to collect all these custom attributes into a
single location—the Parameter Collector.
Open the Parameter Collector dialog box, shown in Figure 35.11, with the Animation ➪ Parameter
Collector (Alt+2) menu command. This dialog box lets you gather a set of parameters into a custom rollout
that can be opened and accessed from anywhere. This provides a convenient way to compile and look at
only the parameters that you need to animate a certain task. Under the menus are several toolbar buttons,
explained in Table 35.2.
