![]() This is done by using the Fractal as a Displacement Map. One of the most popular uses of Fractal Noise is to give elements a glitch effect. Use Fractal Noise to Drive Glitch Animations I’ll set the Blend Mode to Screen, then add a small Ellipse mask to the center, feathering it out. Now, that’s a super-sweet star tunnel. Now, I’ll drag the Star Tunnel comp into my main comp, placing it over the Star Field. This expression is simply using time to drive the animation. To bring it to life, I’ll go back to the Fractal Noise and add this expression to the Evolution property: time*2000. ![]() I’ll turn Interpolation up to 100% and switch the Type of Conversion to Rect to Polar. To create the tunnel effect, I’ll add Effect > Distort > Polar Coordinates to the layer. Creating the illusion of stars streaking by the ship. I’ll deselect Uniform Scaling, and then set the Scale Width to 1 and the Scale Height to 1400. Next, I’ll set the Contrast to 800, Brightness to -100, and open up the Transform properties. In this animation, I’m flying a spaceship back to Earth at an insanely fast speed, so I want to show stars streaking by the ship. For this, I’ll create a new Composition with a resolution of 2000×2000, add a new Solid with the Fractal Noise effect, and name it Star Tunnel. I can keep duplicating the duplicate until I’m happy with the brightness level of the stars. ![]() It’s not bright enough, so I’ll duplicate the Fractal Noise effect and set the Blend Mode of the duplicate to Add. Here I can bring the Scale parameter all the way down to 5. To create the stars, I’ll bring the Contrast to -75, then open up the Transform properties. ![]() Now, I can add Fractal Noise via Effects > Noise & Grain. ![]() I’ll select Layer > New > Solid and name it Star Field. Use Fractal Noise to Simulate Elements Begin by creating a basic star field.įor the first step, I’ll create a basic star field. ![]()
