I think you misunderstand me. It's perfectly possible to have Renaissance buildings with the proper graphics in the Industrial Era. That's a case of indicating a "primary" texture with the iBatchGroup modifier (putting a "0" in this codeline), and a "secondary" texture (putting a "1" in the codeline).
What the problem would be is to have 3 or more citysets linked to the same artstyle.
Someday I have to test this a bit more, but the workload is getting full again.
No no, I understood what you meant. Chamadrys had allowed both the Renaissance and the Meso-American style to display at the same age, for the same civs, by simply adding the ARTSTYLE_MESO_AMERICAN (or something like that) to the Renaissance style.
