An editor tool I designed and developed to convert standard Niagara emitters into lightweight emitters in Unreal Engine.
Originally built for internal production workflows, the converter proved useful enough that I was asked to make it available to the wider Unreal Engine community.
Why lightweight emitters?
Lightweight emitters offer a more constrained particle system designed to reduce simulation overhead. Standard Niagara emitters update particle attributes each frame; lightweight emitters reconstruct a particle’s current state from its age, reproducible random values, and configured modules, without carrying its simulation history forward.
