While Niagara has many of the same particle manipulation methods that Cascade offers, the way you interact and build visual effects with Niagara is vastly different.

Before Niagara, the primary way to create and edit visual effects in UE4 was to use Cascade. The Niagara VFX System is one of two tools you can use to create and adjust visual effects (VFX) inside Unreal Engine 4 (UE4). Once the models are imported, Unreal Engine 5 handles all of the streaming and scaling in real-time, so devs don’t need to worry about draw or polygon counts, or polygon memory budgets. That makes for around 16.5 billion triangles in the scene, not including the room geometry.įurthermore, they said that developers can easily import these high-poly assets (up to 8K) from Megascans or other painting and texturing applications.Īccording to Epic Games, Nanite virtualized geometry means that film-quality source art comprising hundreds of millions or billions of polygons can be imported directly into Unreal Engin5 –/anything from ZBrush sculpts to photogrammetry scans to CAD data-and it just works. They then go on to show a room containing 500 of the same statue, each at the same level of detail. They claim that “No baking of normal maps, no authored LODs is required to achieve this kind of results.

It points to a statue within the demo that is comprised of 33 million triangles. The technology allows developers to use assets in Unreal Engine 5 containing millions or even billions of polygons without hits to performance. Nanite is a “micro polygon geometry” that Epic claims produce triangles at the size of a pixel.
