Hey, can't get the equation for particle world z position to work right. The other two work fine. Is there another equation or another way to link particle world to a null object?

Whereas I realize this question is a month old, I just solved the same problem. You may have forgotten to turn the null object to 3D before writing the expressions.

Thank you for this great tutorial!
Only one problem: I tried to link this effect with a curve and when I play the video the effect doesnt follow the curve well, but goes straight to the points of the curve. Can I solve this problem? Thank you, sorry for my bad english

Wow it was so amazing sir, i couldn't help my self to bring in and believe that der was such a thing as this, anyway it looks pretty well all those instructions were so fine and visible, it really helps me a lot, even though it is sometimes confusing when it comes to the CS6 version of adobe after effects but thanks you so much for teaching it all the way, it as a big help for all those who wants to know more about the efter effects like me, may God continue to bless you.,, Good luck:)

This isn't possible in my adobe after effekts, dont know why but when i'm going to Parent the particle's position with the Null's position, i coudn't parent it position by position, didn't happen enything when i hit "ALT" on the X's position. so i needed to parent the whole particle instead.
I tried to parent the whole particle with the null objekt but it was just wierd, it followed the X's and the Y's position but not the Z's position.

Im running in Windows 7 and with the Adobe After Effects CS5.5 is that a problem?

I'll be happy if anyone answered that for me,( Snirklund@hotmail.com) im a newbe at this animation stuff so explain it to me like i'm a three year old. btw, im from sweden.

Great I'm finished but how do I make the particle cast light on the other layers. I know I could just add another light and animate it but is there another way. Have I missed something

Great tutorial!

I wonder how many other workarounds could be found to give stock AE similar tools as the Particular plugin via presets.

In fact, that sounds like a great idea for a product. You could produce a preset similar in function to Particular but charge considerably less. Even if it is slightly gimped in features, it would probably be something the budget minded would consider. The main reason I don't have Particular myself is I just can't afford it (I just bought AE and Sony Vegas).

When I change the particle radius, velocity, and gravity, my particle disappears. I can\'t see it at all on my screen.

And it won't let me pick whip the Particle to the Null position. Please help!
mart
09/14/2011
same here
hernan
09/14/2011
do the tutorial again, and make sure your camera has the exact same settings as the ones in the tutorial. Also, in order for you to see the particle again you have to animate mkey in the PRODUCER position properies.

Hope it works...

Expresion disabled.
And the info on the location of the expresion.

Please help.

Alan,

Make sure your Null object is a 3D layer

Chad

Hey, great tutorial. My problem is that my particle producer moves around when I move the null object, but there is no vapor trail. It seems the particles just cling to the producer location as I move it through time. Why is that?

hello, i am using cs5 and this is my first project i am working on. now my question is i can not make my solid while have that wiggly tail affect. it does wiggle but i can not make it have the following comet tail. i did manage to find the wiggly affect on the right side under effects and presets only because i have no idea how to write in the bar's ''wiggly3,100'' so i dragged it to my solid white. can u please explain to me how did you write in the box or make the tail affect.. thanks. oh and i also tried the alt+click on position but it will not let me on null only on x,y,z on solid white.. i hope u understand what i mean thanks..
Jake

Try doing an easier effect to begin with, this is more of an advanced effect. Try basic training on the homepage especially if your a begginer

Thanks for the amazing tutorial Andrew but i would like to know how to get the particle to move where i want it to. Where its at now is just random and i would like to be able to control it but still give it that frantic every where look
Luke
05/31/2011
It all depends what you want to do with it? For controlling it, I can either suggest going through it every, ten frames or so, and moving it to the exact spot where you want... Apart from that, if you want it to follow something, I know I may be saying the obvious here but, you could motion track it in?

DFTBA,
Luke.

when i set the gravity to 0 the particle vanished.. I need help
Vincent E Soko
04/08/2011
nice one Andrew! for this i don't need to download the project files, for the first time i want to be creative enough and use my own things.
by the way would it be more creative if you did not add the light but let the lighting come from the light streak itself as it moves,
and hmmm ok the point is how can i do it?

Kevin
03/19/2011
If you want, you can just visit the AE basic training tutorials Andrew has posted ;) it helped me out, and it has some great tips/ tricks plus it all around teaches you many standard stuff about AE :D just find "10 free after effects video tutorials basic training" link under this tutorial or on this site :) (Y)
Nacco
03/08/2011
Thank you for these amazing tutorials!

Tip: if you pick-wip the light to the position of the null object, the light moves with the particle-line nicely.

my probolem, is im working with cs5, and adobe or CC decided to take out the options menu. i dont want a blob at the beg of my line plz hellpppppp
MeTRulez
03/13/2011
All the option have been moved to the Comp and Layer menus at the top. Some are also in the drop down menu of your effect. Just take a tour and you'll find them pretty quickly.

Ah man. Same problem as below. I pickwhip the expressions to the null objects values, and the null is in 3D, and I get that annoying error message.

Error occurred at line 1
Comp: ' Comp 1'
Layer: 2('white solid 1')
Property: 'Position X'

I get it on all 3 axes.

I thought you forgot ";" at the end of the code but it's something else :<
jose
05/04/2011
i got the same thing when this happened on mine.. i am using cs5 and the one he is using is cs4. i did all the steps he did even with the error message and for some reason it still worked only because i saw the attached null next to the solid white. but im not sure what adobe affect u are using.

Johny
12/30/2010
i had the same problem. Just make sure your null object is checked as a 3D object.
Mark
12/28/2010
It usually means something about whatever you alt clicked. I havent watched the whole tut yet cuz something happened to my cc particle world, but i guess thats what it is.

Just curious...The light that was inserted into this comp, can it be parented to the null object as if it's the 'glowing head' of the tracer? I would love to try to have the main light of the scene move around the room (as if it's coming from the tracer)
Eddy
12/06/2010
@Chris Holloman
Yes, indeed you can. Make and expression for position of the light. Type this thisComp.layer("Null #").transform.position
