For example, the library influences sims to read or play chess, so will you not see most of them using off-lot objects unless they’re bookshelves or chess tables.
Both options have the same weight, but the lot type and club rules can affect the choice. When there are objects inside the lot, sims can choose to use them as well as off-lot ones. As you can see below, almost nobody stays idle in the empty lot when this mod is active. So, you will see sims autonomously using objects outside the lot they are visiting if this mod’s lot trait is active in this lot. This mod adds o lot trait that solves that problem. As shown in the picture below, sims seldom use off-lot objects even if they haven’t nothing to do inside the lot, and they’re in a club whose unique activity is to use an off-lot object.
