Unreal Engine 4: Dynamic Crowd Audio


This tutorial shows you how to create dynamic audio for crowds in Unreal Engine 4.


We source our sounds, create a dynamic sound cue, build a Blueprint to scan an adjustable area for NPCs, and look at how we use that data to change sounds dynamically in-game.

Title music by Valkyrie Sound.

Visual assets from Epic Games, grass from Project Nature, and NPC animations from Siarhei Chekolian. All of these visual assets are available via UE4 and the Epic Marketplace.
