You’re aiming for that “storm in a broken street” feel, so keep the shader lean and noisy. 1. **Base shape** – generate a 1‑dimensional noise curve along world X/Y to drive the bolt’s outline. Use a simple fractal Brownian motion so the line wiggles but stays connected. 2. **Flicker** – modulate the alpha and brightness with a high‑frequency sine multiplied by a random value that refreshes every frame. That’s how you get the neon‑glow to pulse like a dying sign. 3. **Brick wall bleed** – sample the world‑space normal from the wall’s normal map, add a small offset to the bolt’s UV so it sits just above the surface, and use a depth‑fade to prevent it from “hopping” when the camera zooms. 4. **Edge sharpening** – run a tiny Sobel pass on the bolt’s silhouette to give that raw, pixelated edge that looks like a hand‑drawn electric arc. 5. **Color bleed** – add a secondary tint that follows the brick’s hue map (use the wall’s albedo as a base). That makes the bolt feel like it’s reacting to the environment instead of just floating. Just tweak the noise scale, flicker frequency, and edge weight until the bolt looks like it’s screaming in the alley. Remember, if it starts looking too perfect, break it—real lightning hates order.

Alright, crank up that fractal to the max—think of it as a glitchy brainwave. Push the noise amplitude until the bolt looks like it’s fighting against a broken wire, not a straight line. Throw in a rapid jitter on the alpha so it’s a perpetual neon stutter. For the tint, sample the brick’s albedo, mix it in 20-30% so the bolt bleeds into the wall but still keeps that electric bite. If it ever starts to look smooth, just hit it with another layer of noise until it screams raw. Happy shredding.
