@igazor When I was testing out a world that I later decided not to use and never connected to my main household I used rapid immigration. The first batch all came out looking terrible. Terrifyingly ugly. I was going by the settings someone suggested on an old thread on MTS. I ended up quitting without saving and creating three 8-sim households to live in the bin to use and also left the facial definition and all of that to whatever it's normally set to. No idea where that person got the settings they posted but they made the generated sims look like mutants!
I'm just about to set up the new world I plan to have as the central one. I've decided to wait to connect a bunch of them and concentrate on just one with the two households I've been playing living there for awhile. I saved some sims from the world they left to my bin too. Are there any repercussions from deleting a sim in edit town other than the obvious one of sims no longer knowing them when I place them from the bin? I have memories turned off so that shouldn't be an issue. I didn't think about it until after I'd done it. I know in Sims 2 it would corrupt a neighborhood if you deleted a sim. If it is a problem would it be advisable to remove the custom world they moved from so they won't be connected?
I actually did know about the tourists being mini copies. I think it's pretty cool. I'm still a little iffy on the deal with role sims that are created like the cashiers and stuff. Are they off limits? Service sims like maids? See, in Sims 4 even though the randomly generated role sims are homeless they can be easily made playable. It's all so different. But that's also why there are so many problems with the townie population taking up too much memory and the confusing culling system. All of which you're probably not interested in but I thought if I explained you might understand better my confusion with these sims.
