Ok, that means you'll need to add motive changes. You'll need to copy and paste the parts that tell the interaction to change motives.
My method for figuring this sort of thing out is to compare a similar tuning file that does what I want and copy paste what I think will work. Compare and contrast. Test, fail, try again. I've gotten much better at modding through the process.
To change it to have fun with painting will depend on what ones you want to have fun. There are several to choose from. you have the paintings that come based on the moods along with what size of canvas you are using. You can also set different ones up to have different amounts of fun as well along with choosing what traits will have fun and what traits will not have fun along with the amounts each trait could increase or decrease. If you want help with it you can PM me and I will help you through it.
