Adding new Buildings

[Tyberius]

I have added a new building to the build prod .txt file, added name, description, review panel icon, info pic, etc, but the building doesn't appear. Is there another file that has to be edited in order to the building actually appear on the campaign build panel?

Check the religion and faction dependencies.

Does the game load up and not show the building? Or does it crash?

Try using the badgerbunny cheat and open up the build menu in game. If it's there it's probably just religion/faction dependencies as Rythmic has said. If it's not there... it should be.
