I have a few questions about how colonisation works in the game, specifically with the AI countries.

First of all, do the Native Americans nations (those who start out in the New World Tech group) colonize on their own? And if they don't, why not?

In all the games I've played with EU3 HttT, I've never seen the Native Americans colonize any provinces near them, so is there some limitation that keeps them from doing this, or are they programmed to not colonize? (i.e. is there some deliberate intent to not have them expand?).

How is all this controlled in the game? Is there some AI file that tells some countries not to try colonising? If so how would I modify it?

Also in a related question, how does colonial range work for the AI countries, because I don't think it works the same way that it does for me. For instance in my current game, Austria (which has only a small coast in the Balkans) managed to somehow colonize Mauritius in 1534, and from there they got a core province which has allowed them to start colonizing the whole southern Hemisphere in the 1600's (they now own Australia and New Zeeland, etc). But I've loaded the game up as Austria and their colonial range should never have allowed them to get Mauritius in the first place (they don't even have "Quest for the New World"), so how are they able to do it?

Also in my current game Burgundy won their war against France and has captured most of that territory and is one of the most powerful countries in Europe, but they haven’t colonised a thing by 1650. In the mean time (and probably helped by the absence of France), England, Holland, Portugal, Castile, Aragon, Milan and even a Catholic Granada have become the major colonial powers. It makes no sense for Burgundy to completely neglect colonisation when they are in fact in a prime position to do so, their AI is just dumb. My only guess is that Burgundy's AI has been programmed not to bother with colonising because it is assumed that they will be beaten by France and France will take that role, well not in this game. I don't understand why the AI can't see its good position and exploit it.

Native Americans don't colonize because they don't recieve any colonists from their religion.

As for the colonial range, you probably need to clear your map cache to get it to work right.

The only way for a non-Christian power to colonize is to:
- Own a coastal CoT, which gives 0.1 colonist / year per CoT
- Take the Colonial Ventures national idea.

It is practically impossible for AI American and African tech group nations to reach the necessary tech level (4) to take their first NI. The only way to do it is to westernize consecutively after getting a higher tech group neighbor (mechanics different in IN and HTTT).

To see a human-controlled Iriquois achieve this feat, look at Prawnstar's Audacity of Hope AAR.

the muslims do colonize , like morocco , ottomans , timurids , however i've neevr seen ming nor japan do it , and they have colonists due to their CoT's
i think the AI won't do it if they are in a low enough trch group

Ah, ok so the Religion is one of the main influences. But that doesn't seem to explain why many Christian nations never attempt to colonise at all, even when they clearly could.

Also, I've sometimes seen Native American and African nations released or rebel against Christian nations and survive for a long time as Christians, but I don't think I've ever seen them colonise anything.

Yeah, if they survive the predator that is Castille, the North African states will colonize. It's not incredibly uncommon to see Morocco expanding into West Africa or Granada make it to South America if either of them get lucky(i.e. France eats Castille).

I've seen subcontinent nations colonise, but never Ming, Manchu or Japan.

Native Americans don't colonize because they don't recieve any colonists from their religion.

As far as I know they're hardcoded not to. Even if you give them plenty of colonists they won't use them (same for all the worst tech group countries).

Does anybody know what files control the AI's colonisation habits? And how they can be modified?

I've been looking through the game folders but haven't found anything like this yet.
