FallUI - HUD is a popular mod that uses the CMMS (Computer Graphics Message Format) to allow user customization of in-game UI. CMMS is a standardized graphical user interface language that controls all sorts of interface elements. The FallUI package can be used to create in-game HUDs for any type of game, such as TESV: Elder Scrolls and Fallout. It also includes a CMMS viewer that makes it easy to view your customizations. The package also contains a FallUI -HUD configuration tool that lets you choose which components of the HUD to edit and edit their properties.

The FallUI - HUD mod is relatively simple to install, requiring only that you download the file from the official website and then copying the files to the game's location. To configure your HUD in-game, first open the CMMS screen, and click Start button to bring up the main menu. You will then need to click the UI tab, where you'll see several choices for what types of widgets and elements you'd like to display on your HUD. To configure FallUI - HUD, click the inference groups option, and move the mouse cursor over any group of widgets that you'd like to add, and then choose the Edit tab. From here, you can enter values into the various fields that will define how those widgets appear or change their properties.

The FallUI - HUD mod is primarily made for people who play Fallout, but there are some cases where it can be useful for other games as well. For example, in Aion, all items are dropped onto the ground when they're picked up; because this makes collecting them easier, FallUI - HUD can be configured to automatically place these dropped items into the right foot container. Other examples of where this HUD type can be helpful include Left Behind, wherein you can specify a destination in the game to return to once an enemy has been defeated, and Enemy SOS, which is similar to a distress signal that you send to another player to coordinate an action that can include gathering the items dropped by your enemy, or moving them to a safe location before picking them up. Using FallUI - HUD in Aion, and other games made by NCsoft, greatly increases the convenience and efficiency of playing the game.
