Candle Flame Shader

💡 This shader came about while I was building Cozy Hearth.
At the time, I used the Water Magic Shader as a quick hack for candle flames — not ideal, but it did the job.

Now here's a proper, dedicated 🕯️Candle Flame Shader — lightweight, customizable, and made to look right from the start.

🎮Check out the live web demo here.

🎁 This package is included in the Neko Legends - 3D & VFX Starter Bundle

🎲 True Per‑Instance Randomness

Toggle on “Use World‑Pos Flicker Seed” to automatically get into a unique flicker pattern —

✨ no two candles ever look the same, even on the same material.

🎛️ Manual Seed Control

Switch randomness off and dial in your own _FlickerSeed for perfectly repeatable flicker timing if that's what you're going for.

⚡ Ultra‑Lightweight & Efficient

• 🪶 No textures or look‑ups
• 🧮 Minimal arithmetic and branching keeps GPU cost low
• 🚀 Optimized for URP and performance‑sensitive projects

🔥 Customizable Flame Profile

• 🔧 Scale, aspect, offset, and “almond” taper controls
• 🎨 Two‑tone gradient from base to tip
• 🌫️ Adjustable blur radius & flame intensity

🧡 Bonus: Included Models

This package comes with a variety of candle models to get you started right away:

• 🕯️ candleFlame, candleFlameHalf. These are low poly flame surfaces.
• 🪔 candleHolder, threeArmCandleHolder
• 🩸 candleMelty, shortCandle, skullCandle

📦 Perfect For

Cozy interiors, festival lanterns, magical spell effects—or anywhere you need dozens of candles to flicker independently without killing performance.
