hi sorry i was away for a while for the holidays and stuff. so what if i build several different levels with ai placed in different locations? i see that the nav mesh (which i have set to static) will be build and be there waiting (costing performance) in all the different locations. i have nav mesh bounds volumes on the persistant level. what is the workflow for setting up multiple levels with multiple nav mesh volumes? how do i stream those in or out? thank you!
