4 slot policies: LIFO, FIFO, LeastUsed, MostUsed
Lease system with configurable TTL and auto-return on expiry
Generation-based handle validation, no stale pointer crashes
IPoolableInterface lifecycle hooks (OnAcquiredFromPool, OnReturnedToPool, OnPoolWarmup, CanBeReclaimed)

Supported Development Platforms:

Supported Target Build Platforms: Windows, Mac, Linux, PS5, Xbox Series X/S, Android, iOS

Example Project : N/A

Important/Additional Notes:

Pooled actors are never destroyed, Return hides them via SetActorHiddenInGame. This is by design.
VFX (Niagara/Cascade) and Audio components must be manually restarted in OnAcquiredFromPool, BeginPlay only runs once at warmup.
