Just the tip: Linking CC Particle World to 3D Null

Here's a quick tutorial to help you make the most of AE's built-in particle system. CC Particle World works in 3D space, but it’s coordinate system is different the rest of After Effects. Use the expressions below to solve that problem by adding them to the Producer settings.



Expressions:
Position X:
x=thisComp.layer("Null 1").transform.position[0]-thisComp.width/2;
x/thisComp.width;

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

Position Z:
z=thisComp.layer("Null 1").transform.position[2];
z/thisComp.width;

Just the tip: Hologram / Projector beams in After Effects without plugins

There's loads of "how to make a hologram" AE tutorials on YouTube, but they all seem to miss out the beams from the projector. This mini-tutorial shows you how to use CC Radial Blurs and Expressions to achieve responsive, changing beams of light.
--------------------------------------------------------------------------------------
Expression used:
L = thisComp.layer("Emitter");
L.toWorld([thisComp.width/2-transform.position[0],thisComp.height/2-transform.position[1],0]);

Just the Tip (a new set of mini-tutorials for After Effects) - Rolling a ball using Expressions

I'm currently prepping a much larger series of tutorials, but to take a break from those, I've also be creating a series of short tutorials for the things I go back to again and again - but not so frequently that I have them memorised. I find myself searching the internet (and the Cow of course) for these tips, but then often have to wade through a 30 minute tutorial - just to find that one thing... that one trick. Well, these mini-tuts are built for that purpose. I hope you find them useful.

This tutorial uses an expression to calculate how much a circle / image should rotate based on its horizontal position. I've then adapted the expression slightly to help you roll 3D objects too.




--------------------------------------------------------------------------------------
Expressions:

2D Layer
diameter=width;
pi=Math.PI;
circumference=diameter*pi;
rot=360/circumference;
Xpos=thisLayer.transform.position[0];
scalePercent=thisLayer.transform.scale[0]/100;
rot*Xpos/scalePercent


CC Sphere in one dimension:
diameter=effect("CC Sphere")("Radius")
pi=Math.PI;
circumference=diameter*pi;
rot=360/circumference;
Xpos=thisLayer.transform.position[0];
scalePercent=thisLayer.transform.scale[0]/100;
rot*Xpos/scalePercent


CC Sphere coming towards camera:
diameter=effect("CC Sphere")("Radius")
pi=Math.PI;
circumference=diameter*pi;
rot=360/circumference;
Xpos=thisLayer.transform.position[0];
scalePercent=thisLayer.transform.scale[0]/100;
rot*Xpos/scalePercent*-1

Makin' the Sun using Video Copilot Orb

Here's a tutorial for creating a 3D Sun in After Effects using Video Copilot's excellent free Orb plugin.  The video starts builds on an earlier Andrew Kramer tutorial for creating a solar surface, but then applies the textures to VC Orb and adds a corona or halo and uses particles and another Video Copilot plugin Saber (also free) to add solar flares.



(I uploaded this video a little while ago, so apologies if you've seen it already, but I realised I hadn't blogged about it.)

Makin’ Pluto: using Cinema4D Lite to create a double planet system with a shared atmosphere

Here’s the last in my solar system tutorial series. This video uses After Effects CC and Cinema4D Lite to create both Pluto and its moon Charon, then use a Loft object and circular splines to create a shared atmosphere linking the two bodies.

Makin' Neptune: Using Cinema4D Lite to create a gas giant

In this tutorial, I'm tackling a different way to create a Gas Giant.  Instead of creating a texture map and applying it to sphere, I'm going to use Cinema4D Lite to create a visible light that looks almost solid.

I will be using Video Copilot's free Orb plugin as well to create the edge atmosphere and the planet's shadow.

Makin' Uranus and using CC Particle World to add its rings

Here's the next part of the Makin' Planets tutorial series, this video looks at how to use After Effects and Video Copilot's free Orb plugin to create the planet, then use CC Particle World to add a ring. There's a slight problem with CC Particle World though, it doesn't allow for things to sit inside it, so the tutorial will use Expressions to create two rings and join them up.




Expressions:
L=thisComp.layer("Emitter Position");
L.toWorld([0,0,0])

Paste these in CC Particle World's producers:
X:
x=thisComp.layer("Emitter").transform.position[0]-thisComp.width/2;
x/thisComp.width;

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

Z:
z=thisComp.layer("Emitter").transform.position[2];
z/thisComp.width;

If statement:
if (thisLayer.marker.nearestKey(time).time > time && effect("CC Particle World")("Position Z") <=0) {

Makin' Saturn: Adding a 2.5D Ring

Here's what I thought would be a challenge, but turned out to be quite straight-forward, (I won't say easy). In this video, I use Video Copilot's Orb plugin to create Saturn with a texture map from Solar System Scope, then I use After Effect's built-in effects to create a ring and have the planet appear inside the ring (with a bit if help from expressions)

Makin’ Jupiter: Animated Textures vs Procedural Clouds

Here’s a tutorial on how to create a texture for the largest planet in our solar system. I’ve actually take two approaches to creating The Gas Giant and in this video, I’ll show you how to both animate a static texture map and use Fractal Noise, Tint and Turbulent Displace effects to reproduce the look procedurally.

Makin’ Mars: Adding orbiting moons and having them cast shadows in Video Copilot Orb

Here’s the next instalment of Makin’ Planets. This time it’s Mars. In the tutorial, After creating Mars, I then create Phobos and link it’s orbit to Mars. Then using expressions and lights, I have it cast a shadow onto the surface of the red planet.

Expressions:
L=thisComp.layer("Phobos NULL");
L.toWorld(L.anchorPoint);

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.
