Ah I got it. Thank you for the step by step directions.
If I may ask one more question:
In the skindefinition file, how do I close out the code? Is it </Element></opt>?
I can't seem to get the UI to show up in the list of skins.
Here's what I got to show just the bottom bar image
<?xml version="1.0" encoding="UTF-8"?>
<opt>
<SkinName Name="Nazgul"></SkinName>
<Mapping ArtAssetID="LetterBoxBottom"FileName=" nazgul_bottom_bar_graphic.tga"></Mapping>
<PanelFile ID="toolbar">
<Element ID="ToolbarField" X="7.5" Y="630" Width="1009" Height="138" Detach="1">
<Element ID="ToolbarFieldMain" X="0" Y="0" Width="1009" Height="138" />
</Element>
</opt>
