Dynamic Text Display on HUDs

Ok I have Xytext working just fine on an in world board, including spreading text across multiple prims. Then I resized everything appropriate for a HUD and it still all works.

Then I attach it as a HUD and nothing.

Tt doesn't reset and load the scripts which I am assuming is the usual behavior.

Far worse is even if I reset them nothing is displayed. The scripts run and all my debug output appears in chat but no characters appear ?

I have set this to operate as 4 linked prims with the root prim being the master and sends the text msg to the display units via link messages.

All works perfectly when rezzed in world

llsetprimitiveparams works on huds, pretty much all texture changiing functions also do.

edit mode.
mouye wheel down.
make sure its visible in the hud, not far outside or showing a transparent backside.
