104 Chapter 2 Setting a Script’s Global Parameters

Application Environmental Variables

The default values of many of the global parameters can be customized via .h

preference files. For example, if you consistently set one or more global parameters to a

custom state whenever you create a new script, you can set custom defaults so that

new scripts are created with your preferred settings.

Custom global values you set with .h files are only applied to newly created scripts.

Once a script is saved, these values are saved within that script, and opening that script

recalls the global settings saved within.

Customizing Shake’s Default Settings

Unlike many applications that control user customizable settings with a preferences

window, Shake provides access to a wide variety of functionality using a system of

user-created preference files. For more information on creating and using custom

preference files, see Chapter 14, “C

ustomizing Shake.”

Script Environmental Variables

The following are variables with states that are not customized via .h files, and are only

saved within Shake scripts.

Custom Variable Loading Order

When you create .h files to customize Shake’s functionality, there is an order of

precedence used to load them.

• The default Shake settings found in the nreal.h and nrui.h files are loaded first.

• Settings in custom .h files load second, according to their own load order.

• Settings in .user files are loaded third.

• Finally, any variables found in a Shake script itself are loaded last, overwriting all

previous settings.
