[GS] [REQUEST] Unique Building Help

[[FADM] Shadow Wing]

Hey there.

i have been trying to add a unique building and while i have the building working (not finisht yet)
i want to make it so its as a unique building to 1 civ in particular EG: Greece
so only Greece can build it.
but i have no idea how to do this... (even after try look into other mods)
Any1 willing to give me a template i can use?
(note its in XML NOT SQL)
in spoiler it shows what i got so far in the NewBuilding_Gameplay.xml
(this is just a test once i am certain it works to wishes i make a proper 1)

You need to give that building a new civ trait. i can tell you how tomorrow...but in the meantime you could take a look at the mod „Civilization specific Wonders“ (or similar name, i dont remember exactly now, was a long night)

in this mod he made it, but for World Wonders. Process is very similar, just that you dont do this for a new Wonder, but for a new building instead.
