XyText v1.2 -- llSetText Alternative
... continued from
XyText
XyText 5face Single Character Texture
Modified by
KermittQuirk 2006/01/19/01 to add support for 5 face prim instead of 3
The best balance between number of textures and number of prims.
Prim setup: Create generic object, insert script to transform it.
