@ The Capo, yes you can, it's the same format as all the others. No need for a download, just take them from colonization, stick them in their own folder, make a new leader in the xml, make a new artdefines folder that linkes to the art. Exactly the same as the ones from vanilla, warlords, bts.
But if you don't have colon. and aren't willing to get it, I'll put it up when I have the chance.

I have what I think is a very important request on a similar note, could anyone help bring all the graphics from Colon. into BTS? This could be a massive graphic improvement for all mods.
I am mostly worrying about terrains (the rest is easy). Light forest, swamp, and the water graphics, are all that are giving me trouble. None of these are available in BTS, so it would be very useful. If anyone brings over any of this I will be grateful. These are the only parts that are having trouble with BTS.
