9GTA-Inspired NPC System in UE5 – Part 3 – Pooling
In this video, I continue building a Grand Theft Auto-inspired NPC spawner in Unreal Engine 5. This is part 3 of the system where I introduce object pooling to dramatically improve performance when handling dynamic NPCs.
🔷 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
