When you run the program, it loads several auxiliary files and uses their settings. In some cases, the program also updates files when you change settings and when you quit the program. In general, you don't need to work directly with these files, but it's good to know about them. Among the auxiliary files the program uses are:
gmax.ini û This file gets updated upon starting and quitting gmax, as well as when you change most Preferences settings. It contains values relating to program defaults, including the graphics driver, directories used to access external files such as sounds and images, dialog positions, snap settings, and other preferences and default settings. If you edit this file, be sure to make a copy first, so you can return to the original if anything goes wrong.
gmaxstart.gmax û At startup and when you reset, gmax looks for this file in the Scenes directory specified in Configure Paths, and if found, loads it. This allows you to specify the default state of the workspace whenever you start or reset the program. For example, if you always use a ground plane, you can make it the default setup by creating one, then saving it as gmaxstart.gmax. If you save a different file over gmaxstart.gmax, you can return to program defaults by deleting the gmaxstart.gmax file, then resetting the program.
gmaxstart.cui û This is the default custom user interface file gmax uses. You can load and save .cui files, and set the program to use a different default .cui file. See Customize Menu.
plugin.ini û This file contains directory paths for gmax plug-ins. Most other paths are kept in gmax.ini, but plugin.ini is maintained as a separate file because third-party plug-ins often add entries to the list at installation.
Note: It is possible to use more than one plugin.ini by nesting additional paths in your plugin.ini file. This can be very useful for allowing an entire network of users to share one plugin.ini file, making the system easier to maintain for the network administrator. For more information, see Network Plug-in Configuration.
startup.ms û A MAXScript file that automatically executes when you start gmax. For more information, see Startup Script (Glossary).
splash.bmp - To substitute a custom splash screen (startup screen) for the default image, copy any Windows Bitmap (.bmp) file into the program root directory and rename it splash.bmp. The program will thereafter use this image at launch.
