How to make a race more agressiv / passiv ?

[Ben]

Hi

I'd like to change the attitude of some races in se4, some should become more agressiv (a race of conquerers,hate peace, aso) and some more peaceful (like trade and peace, do not declare war against other races, aso... ).

Which files of a race do I have to change to make them more agressiv/peacefuel?
( if there is a tutorial about it just give me the link, thanks )

I think you change the AI settings to angry over planets higher.

Also look at the AI_Anger file.
