GTA-Inspired NPC System in UE5 – Part 4 – EQS Powered Spawning
16GTA-Inspired NPC System in UE5 – Part 4 – EQS Powered Spawning
In this fourth part of my GTA-inspired NPC spawner system for Unreal Engine 5, I show how to integrate Unreal’s Environment Query System (EQS) to intelligently place NPCs around the world. The system is optimised, location-aware, and rule-driven, allowing different types of NPCs to spawn depending on where the player is. EQS is used to find suitable spawn locations hidden from the player to prevent pop-in and preserve immersion.
🔷 What You’ll Learn in This Video:
✅ Implement an object pooling system for NPCs
✅ Spawn and despawn NPCs efficiently
✅ Handle location-based spawning rules
✅ Optimize a large open world with minimal performance hit
