Hi I want to add some strategic resource modifiers to some techs. Say, I would add +25% iron from Steel and Metallurgy, +25% to all resources from Industrialization and so on. But seems there aren't any tables to do it. The only thing seems i can do - add modifier to all resources by creating a dummy policy. But I would like to add modifiers for individual resources like I said above. Maybe some tables/functions exist in newer VP? Or you know another way for it? I found single resource modifiers in traits table only. But I have no idea how to use it for my task.
