Is there a way to make resources yield Culture? Improvements got the <Culture> tag, but i don't see a way to add culture to resources.

doesnt look like it. Resource_YieldChanges table uses the Yields which doesnt have a culture yield

how about a building that can only be created if the resource is within the cities borders (like the mint), and you set the desired culture level on that building?

while not exactly what youre looking for it could yield the same results.

or a new improvement specific for a resource that gives cultures

My idea was to increase the yield on all resources and mix around the yield to keep it interesting, but I guess I need to do workarounds when it comes to culture.

Adding an own wheat build goes against what I'm trying to do in my mod, that bonus resources are nice, while luxury resources defines cities. However I guess I can add 2 food to wheat without improvement, then 1 food and 1 culture with improvement. I just have to add a unique farm improvement for wheat so that research does not mess up the stats.
