Edit - here you go:
Code:
<TopLevelControl name="ZO_RightFootPrintBackground" virtual="true">
<Dimensions x="930" y="750" />
<Anchor point="RIGHT" offsetY="20"/>
<Controls>
<Texture name="$(parent)Left" textureFile="EsoUI/Art/Miscellaneous/centerscreen_left.dds">
<Dimensions x="1024" y="1024" />
<Anchor point="TOPLEFT" offsetX="-65" offsetY="-75" />
</Texture>
<Texture name="$(parent)Right" textureFile="EsoUI/Art/Miscellaneous/centerscreen_right.dds">
<Dimensions x="64" y="1024" />
<Anchor point="TOPLEFT" relativeTo="$(parent)Left" relativePoint="TOPRIGHT" />
</Texture>
</Controls>
</TopLevelControl>
That remembers me - I actually need to use that manual creation in my own addon FastReport as well.
(dont let the names misslead you - you need both of them)
