Makin' a Nebula with (just) CC Particle World

COW Blogs : Graham Quince's Blog : Makin' a Nebula with (just) CC Particle World
In this tutorial, I use Adobe After Effect’s built-in particle simulator, CC Particle World to recreate the look of a nebula in space. Turbulent Noise is used to give the particles a texture and at the end I add the remnants of the star which went supernova to create the cloud of gas and dust.

It gave me the chance to demonstrate CC Particle World’s Resistance property – which is always a little tricky to master.

I use a few expressions in this tutorial, you can copy them from here:

Marker linked to Particle Birth rate:
if (marker.key(1).time >= time){
effect("Birth Amount")("Slider")
} else {

CC Sphere X Rotation:
planetpos=effect("CC Sphere")("Offset");
x=length([planetpos[0],planetpos[1]], [campos[0],campos[2]]);
value+radiansToDegrees(alpha) ;

CC Sphere Y Rotation:
planetpos=effect("CC Sphere")("Offset");
value+radiansToDegrees(beta) - 90;

I also reference an ealier tutorial of mine, Linking CC Particle World to a 3D NULL:

CC Particle World link to a Null Expressions:
Position X:

x=thisComp.layer("Nebula NULL").transform.position[0]-thisComp.width/2;

Position Y:
y=thisComp.layer("Nebula NULL").transform.position[1]-thisComp.height/2;

Position Z:
z=thisComp.layer("Nebula NULL").transform.position[2];

Here you'll find a bunch of tutorials for using After Effects (mainly). I have a YouTube channel, called ShiveringCactus (long story - not funny anymore) where I post the videos.
