In this video, we look at a high-level overview of the Niagara VFX system used in Unreal Engine 5, from exploring each stage of the Niagara pipeline, including systems, emitters, and modules to examining what goes into making an effect and the associated range of tools. Begin Play is a series of videos designed for experienced developers who are transitioning from other engines like Unity to Unreal Engine 5.

Small comment. I noticed the schematic to download is slightly different than the one you are using in the video tutorial - in the video the Debugging group is on the bottom left, while on the schematic its on the top right. I thought I’d let you know in case you wanted to keep them in sync or wanted to comment on the differences.
