Unreal Niagara Data Channels QuickStart Guide
🕑 Added 2025-09-19 03:45:08 +0000 UTC
In this unreal engine tutorial, I am going to show you how to setup a simple Niagara data channel system to spawn bullet impact particles on the first person shooter template. NDC (Niagara data channel) can be viewed as a way to communicate and share data between blueprints or game code and Niagara systems(CPU or GPU). The advantage of NDC based approach for spawning impact particles over traditional spawn Niagara system method is, performance. In the traditional method, we would be spawning a particle system everywhere we get a bullet impact. But the NDC way will use a shared set of Niagara systems to re-use and spawn impact particles on any given location. This would give us a significant performance advantage.
