This effect is a combination of Blueprint, Niagara, shaders, and particle systems designed to generate lightning and electrical effects.

The main goal was to create a system suitable for lower-performance platforms, including mobile devices, with a very small GPU cost.

I added additional environment content to make the scene more demanding and provide a more realistic performance test, while keeping the VFX itself lightweight and efficient.

The effect uses a combination of shader-based techniques and particles to achieve the final look.
