ok so i have not seen any tutorial that answers the questions of so many people out here and recently i was myself wondering if it was possible. If you want to change the movement points for infantry, cavalry and siege on the campaign map then listen up.
First go to descr_campaign_db.xml in mods/stainless_steel_6/data
when you open it go to the bottom and add what is colored:
note: this is just an example. You can put whatever values you wish for cavalry, infantry and siege.
I have just tested it and it does work. (i tested it by giving cavalry "7.00" to be able to see any difference)
i don't know if anyone else had already found out about this (cavalry and infantry) but i haven't seen any.
This is different to the changing character movement points (general, captian, admiral, spy, assassin, priest, heretic, witch, inquisitor) which you can change by going to descr_character.txt
