[edit] Myriad Lite Meter

Many people prefer a hovertext meter to let others see the in-character alias name of the player and see the relative damage or health of their opponents during combat.

[edit] Setup

1. Create a cylinder 0.025m for X and Y, and 0.5 meters for Z
2. Set the texture to "Default Transparent" and set the transparency to at least 2%
3. Drag and Drop the Myriad Lite Meter script (below) from inventory into the object
4. Take the meter into inventory.
5. Attach the meter object from inventory to a convenient spot, such as an ear or eye.
6. Press CTRL-ALT-T to "Show Transparent"
7. Edit the position and rotation of the meter attachment.
8. Detach the meter back into inventory to "save" the new default attachment point.
9. Attach or wear the meter when designed.

You should see "waiting for update" at first, which gets replaced with your character sheet alias and health on the next meter update event.
