A live, editable VFX system — in your engine.

Describe the effect you want — “realistic campfire, layered flame core with rising embers,” “swirling portal,” “glowing magic circle” — and Libra builds it for real, inside Unreal Engine. No hand-authoring emitters, no hunting through node graphs.

Under the hood, Libra plans out the exact sequence of engine calls it needs, then validates every single one against your live project before it runs anything — so what you get isn’t a guess, it’s a real, working Niagara system you can keep editing.
