Lightning VFX (BiRP)

A lightning strike that does more than flash

When a lightning moment has to read clearly in a game scene, it needs more than a bright bolt on screen. Lightning VFX (BiRP) gives that strike a full visual setup for Unity, combining advanced particle system configurations, a hand-drawn lightning texture, custom shaders, and supporting components for automatic variation, dissolve, and post-processing effects.

The result is a lightning prefab that fits into scenes where the effect has to do several jobs at once: hit the environment, affect the camera, and stay adjustable while the rest of the scene keeps running. A realtime WebGL demo is included, which makes the motion and layering easier to judge before the effect is placed into a final shot.

What the prefab includes and how it is organized

The package centers on one lightning prefab and a mobile variant. Inside that setup are 22 unique sub-systems that can be configured, so the effect is not locked into a single static look. Unity's native particle system is used to set up nearly every part of the effect, which means the structure stays editable rather than closed off behind a fixed animation.

• 1 lightning prefab plus a mobile variant
• 22 configurable sub-systems
• Lightning shader with per-particle randomization, erosion, and remapping
• Grayscale Invert and Radial Blur post-processing shaders and materials
• A custom post-processing blending system

The shaders also expose properties for additional control, and the quality of the radial blur can be adjusted. That makes the effect easier to tune for different scenes without changing the overall structure of the strike.

Light, shake, and visual force-feedback

One of the strongest parts of the setup is that it does not stop at particles and glow. The effect uses real animated lights that cast shadows and illuminate the environment, so the lightning can brighten the surrounding scene instead of sitting on top of it as a flat effect. That matters most in darker shots, where the bolt has to do the work of revealing the space around it.

Camera response is handled with specially made Cinemachine components for camera shake impulses. The post-processing setup is tied into that motion as well, with a blending system that increases visual force-feedback when the camera is closer to the effect. The package presents the strike as something the viewer feels as well as sees, and the lighting, shake, and post-processing all push in the same direction.

The shader layer adds more control on top of that. Per-particle randomization, erosion, and remapping give the lightning more variation, while the Grayscale Invert and Radial Blur materials support the visual hit at the moment of impact. These details make the effect useful when a scene needs a sharp burst rather than a simple animated line.

Where it fits in a Unity workflow

Lightning VFX (BiRP) sits naturally in a particle and VFX workflow for Unity scenes that need a lightning strike with camera response and lighting attached. Because it relies on the native particle system for most of its setup, the effect can be customized in place instead of being treated as a fixed final render. That makes it practical for scenes that need iteration around the shape, timing, and intensity of the strike.

The package also includes a PERFORMANCE MODE for mobile or low-end hardware, which gives a direct way to shift the effect when the target scene needs lighter rendering. The original Unity version is 2022.3.5, the render pipeline compatibility is listed for Built-in, and the package type is unitypackage. The current version is 1.1.0, with a latest release date of Aug 07, 2023 and a first publication date of Aug 02, 2023.

Other package details are just as compact: the file size is 3.2 MB and the asset count is 62. The release notes mention preparation for URP cross-launch and the initial release. In practical terms, this is a focused lightning effect package for scenes where the strike needs to affect the environment, the camera, and the post-processing pass at the same time.
