Ezlightning stands out in the Superhive library for handling lightning through a fluid-sim-style workflow Blender users already know, covering both keyframed storm bolts and controlled arcs from a single panel, with physics-based simulation noted as coming soon.
Ezlightning is a Blender add-on used to spawn lightning dynamically in a scene, for storm effects or electricity in a sci-fi shot. The lightning can be baked to generate keyframes and shaders for rendering through an optimized simulation process. Its simulation domain is dynamic, much like Blender's fluid sim, keeping setups quick and intuitive, and a particle system with many options lets you tweak the simulation for performance and for the effect you want.
The add-on covers a few approaches. Traditional lightning spawns fully keyframed for stormy scenes, keyframed for renders only or shown in the viewport for easier handling. Controlled electricity produces arcs from characters or sci-fi objects using particle spawn polarity, control points, or a specific origin, which the developer notes suits graphic design and science-experiment scenes. A static origin can be positioned or animated to control where lightning spawns.
Objects inside the domain can be ionized so lightning strikes them, and you configure the rest through settings such as spawn frequency, particle polarity, simulation resolution, and color, all within one panel. It targets Blender 3.6 to 5.0, and fully simulated lightning using physics is coming soon.
Ezlightning is best for blender artists creating lightning for stormy scenes or electrical arcs for sci-fi and science-experiment shots.
Ezlightning is completely free to download and use.
Ezlightning lists compatibility with Blender versions 3.6 through 5.0. It's shared under the GPL license and is usable across several render engines, including Blender-Internal, Blender-Game-Engine, Cycles, Eevee, and Octane. Because lightning can be baked into keyframes and shaders through the simulation process, the effect carries through to rendered output. If you're on a version within that range, check the developer's page for the specific setup notes and any details tied to your exact Blender build before installing.
Ezlightning uses a dynamic simulation domain that behaves like Blender's native fluid sim, so the setup follows a workflow many Blender users already recognize. You can move and scale the domain to fit your scene both before and after baking. It runs a particle system with options you can tweak for performance and for the effect you want, and the domain, simulation, and render settings all sit within one panel. Baking then generates the keyframes and shaders through an optimized simulation process.
Ezlightning supports controlled electrical arcs that spawn from characters or sci-fi objects. You can shape this using particle spawn polarity, control points, or a specific origin, and the developer notes it suits graphic design and science-experiment scenes. There's also a static origin you can position or animate to control where lightning spawns, which fits static electricity and animated objects. For stormy scenes, it can instead spawn fully keyframed lightning, either for renders only or within the viewport for easier handling.
Ezlightning can ionize objects placed inside the simulation domain, which allows lightning to strike them. Beyond that interaction, it exposes settings such as spawn frequency, particle polarity, simulation resolution, and color, so you can tune the result toward the effect you need. The developer also notes that fully simulated lightning using physics is coming soon. For now, the effect is driven by the particle system and the baking process that generates keyframes and shaders for your render.
Ezlightning is listed as free in this catalog. Licensing and availability can change over time, so check the developer's page for the current terms before you rely on it for a project. The add-on is shared under the GPL license and is marked as a Blender Development Fund contributor. Documentation is listed among its resources to help you get set up, and a demo video is available if you'd like to see more before deciding.
