Aurora Spline Blueprint is a spline-based system for creating animated auroras in Unreal Engine.

Place the Blueprint in your level, then shape the aurora by adding and moving spline points. The required spline mesh segments are generated automatically, allowing you to create long, curved auroras.

Each instance can be adjusted directly through the Details Panel. Height, segment length, colors, brightness, and opacity can all be changed without editing the Blueprint or material.

Animated material noise creates the billowing motion within the aurora, while optional spline movement slowly shifts its overall shape.
