The effect parameters change accordingly. Select the Brightness you want for the Firework. Set the Density value to define how dense the streams of sparks are. The Fall speed determines how much the streams of sparks are seen to 'fall' as the firework appears, bursts and fades. Modifying Hue change causes the complete firework to vary between other colors during the animation.
Completeness corresponds to what stage the firework is in.
Initial speed controls whether the firework bursts towards the right or the left. Increase the Hue Variation to create multicolored fireworks. To select individual colors for a firework, change the Star color and Sun color . Choose the Ambient light that you want for the background of your firework. Darker backgrounds make the firework's colors more vibrant.
