Which buildings show on the Campaign Map?

Or put another way - the campaign map settlement models change when you upgrade certain buildings, chiefly the walls.

Is it possible to (say) create a government building (or any other building) on a certain level that would show a large towering edifice in your campaign-map settlement?

These models are all culture rather than faction-specific I believe, though I have not found the file for such models as of yet.

It is possible to edit these models (I can't remember where they are sorry). The model changes when the walls change or the settlement level changes.

I highly doubt if you can trigger a city model to change when building a new building (except walls).

The strat changes are presumably all hardcoded. Only core_building and defenses trees do anything to the model (and the port line modifies the port, of course). You can change the models they get changed to if you want, though.

Is this the (after running XPAK) folder for the cities?

C:\Program Files\Activision\Rome - Total War\Data\packs\DATA\UI\ROMAN\CITIES

but surely these are just 2d pics? Where are the cas files and textures for the campaign map settlement levels (walls & inner city buildings).

The settlement & wall strat models (for each settlement size per culture) are defined in descr_sm_settlements.txt

I have tried to introduce per-faction buildings but this file seems only to accept per-culture ones. No surprises there.

I am left wondering though why the comments at the beginning of the file infer that per-faction designations can be made (in new code blocks) - anyone experimented with this?

Yeah I've tried a bit, but either there's some particular syntax required or else it was something that wasn't implemented (probably the latter). It's a shame, as faction-specific or even region-specific settlement models would be great to be able to do.
