Different Era Graphics question

[Ekmek]

I heard that PTW will have different era swordsman graphics. Has anyone done this with 1.29?
Or anyone know how?
I've seen multiple ini files on the eras but I haven't really dug around there and don't want to mess anything up. Any of the more experienced guys figure this out?

That way I can make a standard soldier/mercenary unit or something that the graphics will upgrade.

thanks?

You can do that by having folders for the unt with the era name (like workers, leaders, ect.), it will automaticly change them for you but the units_32.pcx icon will not change (this will be fixed in PtW).
