Sim Spawn Overhaul thumbnail
This mod lets you control where and how NPCs spawn, fix weird spawn behaviors, and improve immersion across worlds.

Sim Spawn Overhaul by lotharihoe is a gameplay tweak mod that changes how and where Sims and NPCs spawn in the worlds. It addresses odd behaviors like characters wandering between worlds without reason, inappropriate NPCs in certain locations, and stray animals or supernatural Sims appearing where they do not belong.

Key Features
  • This mod adds a settings menu that lets players control NPC spawn behaviors via a “shift-click mailbox” menu with testing cheats enabled.
  • It allows defining world compatibility so NPCs from certain worlds spawn only or mostly in ones you choose (e.g. restricting Sims from one world showing up as pedestrians in another).
  • It fixes specific spawn issues: stops children from spawning at gym lots where they stand idle, replaces “fake vampires” with proper vampire NPCs, ensures homeless park sleepers are properly labeled, and enforces correct neighbor-Sim filters.
  • Also ensures bouncers for VIP doors spawn reliably whenever you load a lot with a VIP entry, avoiding missing appearances due to timing issues.
