Happy Helloween

Hi guys, I was doing this work during the Halloween holiday! This scene demonstrates four Niagara systems : firefly, amber fire, candle fire, and falling leaves. Besides vfx, I also do some of model and materials to enrich the scene.

Candle Fire

I used Scale Color to shape the flame and make it taper upward like a real candle.

Light Render

Added a Light Render so the flame actually illuminates nearby pumpkins and candles, making the effect feel alive. To control the color, I used a Random Range Color between yellow and red to simulate the warm, flickering fire tone.

Amber Fire

This scene looks like a cool town with purple point light, and candle fire is the only warm tone in this scene.

I wanted something that looked more energetic and burning, like glowing embers rising through the air to enrich the scene. Therefore, Amber Fire is the best choice.

A custom material shaped like a cloud to give the particles a soft, organic shape.

Combined with upward velocity and noise forces, it creates a feeling of heat and energy.

Firefly

I used a Vortex Force to make each firefly move in gentle circular or spiral paths instead of straight lines.

This creates a natural floating motion, as if they're drifting through the air.

Each firefly uses a Light Renderer and Color over Life to softly glow and fade, giving it a magical, nighttime look.
