The first time you run the UI Editor, you will be prompted to specific program settings. The only required setting is your Atlantis Directory. The Atlantis Directory must indicate the base directory in which you installed Trials of Atlantis (the directory which contains camelot.exe).
The Auto-load Most Recent Project at Startup setting can be unchecked if you would like the UI Editor to load your last project automatically at startup. And, if for some reason you would like to skip by the beautiful DAoC UI Editor splash screen, uncheck Show Splash Screen.
Preview Size Indicates the resolution of the Preview Area. Setting the preview to different resolutions is a quick and easy way to get a feel for how a UI will look when playing the game.
Show Background Image By default, the UI Editor displays a background image in the preview area. This image is intended to help you get an idea of how your UI will look when running the DAoC client (its especially helpful for testing translucent textures used in a UI.) Uncheck this option if you'd prefer a solid background, which can be more helpful when laying out controls.
Background Image If you would like to try out other background images, simply use this file selector to choose one of your favorite DAoC screenshots. The specified background image is only shown if Show Background Image is checked.
Background Color The background color is used in the preview area when Show Background Image is unchecked. It is also used for other previews such as the template preview, asset preview, and texture editor.
Selection Color The selection color is used when highlighting the currently selected window or control.
Tag Line The "Tag Line" is an optional line of text that, if specified, will appear in a comment at the top of XML source files saved with the editor.
Indent Spaces Number of spaces to indent nested elements in the XML source file.
Empty Lines Between Elements Number of black lines to insert between elements in the XML source file.
Encoding The XML encoding in which to save files. The default is "European (ISO-8859-1)" which will produce source files that can run on both US and European clients.
Warn Before Deleting Nodes Leave this checked if you would like the editor to ask politely for you to confirm any attempt to delete elements in your UI.
Toggle Window Visibility on Selection By default, when an entry in the Window List is selected, the corresponding window is shown in the Preview area. If the entry is clicked again, it will simply be highlighted. Check this option if you would like the second selection to instead close a visible window.
Remember Dialog Sizes When this option is checked, the UI Editor will remember any changes you make to the size of property dialogs.
