Create a New Composition that is 1000 x 1000 pixels in size and set the duration to 10:00. Name the composition Fractal Sun and click OK.

New Composition
Create a rather large composition to begin with, we'll need the large comp size in the next installment.
[an error occurred while processing this directive]Create a New Solid by pressing Command+Y on the Mac or Control+Y on the PC. Name the layer Sun and make it the same size as the composition. Select a rather dark orange color (243, 93, 0) and click OK.

New Solid


From the Effects menu select Render>Fractal Noise and apply it to the Sun layer.

In the Effect Controls Panel use the following settings:
Fractal Type: Dynamic Twist (this gives a nice swirl to the star matter)
Noise Type: Soft Linear
Contrast: 108
Complexity: 6
Opacity: 60%
Transfer Mode: Hard Light

Fractal Noise Effect
The Fractal Noise settings. Fractal Noise is only available in the Production Bundle of After Effects.


This results in a pattern that looks a bit dark, but works well with the intended end result (the sun starts spinning slowly and progressively gets faster, meaning a cooler object at first and then as it spins faster it warms up more).

Fractal Noise Applied
The results of applying Fractal Noise to the Sun layer.


For the moment, let’s leave the Fractal Noise effect alone and deal with how to make the flat layer look more like a ball. While there are several plug-ins on the market that can take a layer and turn it into a ball, we can fake it just as easily with the Spherize effect.

With the Sun layer selected in the Timeline, apply the Spherize effect from Effect>Distort>Spherize. The Spherize effect does as the name implies – it distorts the image around a center point to give the illusion that it is wrapped around half of a sphere.

Spherize
One of the more basic effects in After Effects.


In the Effect Controls Panel set the Radius to 200 and the Center to 500, 500.

There isn’t much to this effect, and at the moment, it might be very difficult to see the effect.
