Yes I'm using it , I was using the settings of the 3D RPG ACTION tutorial as base and then i custom it a little .
Here is the actual settings even if i tried multiple of them , as you can see the HUD as a limit display + a condition but it activates even if the condition is not fullfill.Basically looking with the camera in the direction of the combatant spawned in the party menu(even deactivated and not in the menu) activate the HUD and it become deactivated once the camera is not looking it.
The link contain 3 images with the settings.
As for the spawning I called dummies is kinda custom , a sub menu with combatant HUD is showed when clicking on a HUD click on the screen, theses list is only a combatant menu part that show HUD and containing themself HUD click to make appear a "ADD" or "remove" button.
If i click on the add button a check will be made to know who is the machine object of the clicked HUD and based on that make spawn the combatant using a simple spawn combatant without a faction( even if it seems it get affected to player automatically).
the part that make the spawn look like this :
