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]);

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.
