Well, then you're probably not doing it right I did something similar with sparxx UI (before I realized they had a patch for less spell slots), so I'd be shocked if it wasn't similar in other UIs.
<StaticAnimation item = "BW_BuffBackground2">
<RelativePosition>true</RelativePosition>
<Location>
<X>150</X>
<Y>262</Y>
</Location>
<Size>
<CX>100</CX>
<CY>152</CY>
</Size>
<Animation>Buff_BackgroundRight</Animation>
</StaticAnimation>
<StaticAnimation item = "BW_BuffBackground3">
<RelativePosition>true</RelativePosition>
<Location>
<X>150</X>
<Y>392</Y>
</Location>
<Size>
<CX>0</CX> <!-- this is it right here -->
<CY>0</CY> <!-- ...and this little puppy too -->
</Size>
<Animation>Buff_BackgroundLeft</Animation>
</StaticAnimation>
Size to zero has no effect on the spell gems sadly.
Do you have any idea how to anchor something to the bottom? I can't find any basic documentation on any of this stuff anywhere.
