This Geometry Nodes setup generates a retro, stylized thunder effect procedurally on any mesh. The product includes one primary Geometry Nodes group, two emissive materials, and four custom compositor nodes designed to simulate a vintage video game aesthetic. The nodes primarily utilize Blender's Shortest Edge Path algorithms to map the electrical arcs across the surface geometry.

The system works efficiently with curved meshes, while sharp-edged models may benefit from beveling paired with a decimate modifier to manage performance. The thunder effect achieves optimal visual results when EEVEE's bloom is active, though the solution is fully compatible with Cycles setups. Users are advised to disable the integrated Remesh modifier during initial parameter adjustment to maintain viewport responsiveness before enabling it for Final rendering preview.
