) it didn´t work well, the program showed me a warning message 'Warning AfterEffects, incorrectly argument, expression disabled: error in line 1' then when i was trying to do this proyect i couldn´t finish it, the point with the particle didn´t work well... So i would like to read how to use those functions or if you can tell me what´s wrong with this line? i´m using After Effects 7....Thanks
PS: Sorry for the english i´m Latin-American...
First of all i would like to thank you about your great Tutorials .. your way in explaining is very uniqe
But i have some question to you it is about
Simulation ... actually i don't have this list of CC , and sure i don't have CC particle World

keep up the good work me friend,

On the one I did from scratch, it sometimes looks fine before I ram preview it, but when I use ram preview it looks different than what I see from scrolling through the effect in realtime. It seems kinda complicated just to get a simple cool effect, I hope someone will develop a new plugin at some point to animate this way ^^;
Hail Caesar !!
We live in Cuba , and we follow every tutorial you put here, like a TV serie , like someonesaid here...the fact of you been an awesome online teacher is known already,,,,and we have certain connection troubles , but still we are learning, we would buy your package but the fact of us been in Cuba, prevent us from buying them , is there any other way of get them ?....pliz.. :(
igual muy bueno ,gracias..
Thanks very much, keep up the good work, and the jokes ;)
Henry
please can you tell me if it's possible to remplace the ball light by a particule system from ParticuleIllusion ?
thx
Best Regards
Great tutorials though. love em.. i should buy one of your dvds
i do have a question though, is it posssible to make the particle more smooth and round?
Cheers and thanx for a this great knowledge you share with us.
Thanks for a great tutorial, but I cant do the most interesting part because every time I bring the values for the particle down to zero, its invible or not even there so when I adjust the x,y,z position nothing changes so Theres no point in even creating the null object. this is so frustrating.
im just having trouble when you are switching everthing in particle effects to zero... im not getting that lone single particle. its fine before i switch the production and physics off but as soon as i switch it off everything dissapears
this is torrmenting me and driving me nuts. could u please help me?
i am praying there a simple switch im forgetting for this.
plz do help.
Thnx. God Bless U

i wonder if u can tell something about exporting video for web.
your tutorials are big size and they download very fast. wich format do you use? and settings use for?
Nobody could count your students, it's an immortal vitue,
May you live long.............................
I'm tried using this to make a moving line(like this: http://www.beam.tv/beamreels/reel_player.php?jqbvsptxVy&resize=1 ) but I couldn't do it. can you help me out with this? I can understand if your too busy, but i would really appreciate it.

Just a quick question - If you wanted it to wiggle and then draw a specific shap (logo for example), can you easily do this with the same null object, or would it be better to have the null with the wiggle expression finish the same frame that another one starts (to draw your shape)?
Cheers for any advice
Is there a way to do something like this 3d stroke effect but with text?
I need to purchase the cycore effects - and the cycore site is for a better term 'lacking' - I am running AE7 and have basically opened it up today so I know nothing...
is 6.5 the correct version to order ($49) - or do i need the HD version ($249)
I understand that the package is on the install disk - but the support group does our installs and doesn't understand how this works - their response: "its already installed" - I cant wait 4 months while they try to figure it out :)
Thanks in advance!
I am having a little trouble with this one and was wondering if you know where I went wrong.
I was trying to do the 3D Stroke Effect tutorial and I get as far as setting all the physics to zero and then I don't even have a spec on my screen. I see nothing, even when I continue on with the tutorial, nothing is there. I tried moving the playhead and played with the Producer positions. Only when I add gravity or velocity I see the particle. When I do that it's way to big and my streak doesn't look like a streak. Any ideas.
I am using CS3 on my Imac with intel.
Thanks
you are really good teaching, and also funny (that's make you a better teacher
thanks for all this tutorials!!
but..i'm having some problems with it, Im using CS3, I set up particular world as you said, all "0" (only logetivity, and birth rate are in defoult), the white object (solid)is not in a 3D layer, but, i don't know why, it just doesn't work, i cant see any "particle"
do you guys can help me? what can be wrong with it?
PS: sorry for my english, I'm brazilian, living in Canada, so i still learning english
Thanks guys
I like this tutorial, but I don't really like it if you say "with built-in tools from AE7" and it's not the truth
My CC Particle has the same green lines (X) on the screen. It seems to be not free... so would be helpfull if you say/write that somewhere so I don't have to watch the video and wake up like "huh... made for nothing"
Ricky
Thanks for the tutorials.
Really appreciate your work. Keep the tasteful stuff coming. If you could do more text tutorials that would be amazing, good ones if possible, the level of JUSTICE, music videos.
Thanks a million
Same problem as "brazil canada" and others, when I turn everything down to zero, everything disappears, I dont have a single particle like you do.
Keep up the good word, you're great!
wanting to do a video with these moving around me,
possible?
i can tseem to figure out how to make them go behind me
its not like photoshop where i can cut my self out and paste behind...
Greetings from the Caribbean, just dropping you a few lines to say that I appreciate for efforts here man, I'm a print designer and have just started off in motion graphics. Your tutorials really help me along that part. Keep up the good work, you're good at it.
Thanks a mil.
Thanx
Thanks for the tutorials. and good luck for you .
i'm a new user of Aftereffects and my english isn't the best!...I copied from another comment...
"I cant do the most interesting part because every time I bring the values for the particle down to zero, its invible or not even there so when I adjust the x,y,z position nothing changes so Theres no point in even creating the null object. this is so frustrating!"

Thanks a lot.
May God bless you
first of all, thanks for the awesome tutorials.. some give me some trouble but still i can mostly use them for my school work.
just notifying also for everyone else who reades, this tutorial does not work as nice in widescreen. there's a problem with the particle height expression. i'm trying to figure it out and i'll post it as soon as i do
greetz
as the result of my previous post, no formula would probably solve this, but if you do want to make a widescreen edit of this,
make sure you use a "square pixel" composition
that's that... this is an awesome tutorial by the way, definitely going to use it for school
Thanks Tutorial
But i've got the same problem like the others, I've downnloaded the CC-Particle World from the HP für free. Don't know how to deaktivate the green lines, or is it, cause it's for free?
your tutorial is very exellent. congratulation. But i've a problem when i change position effect: cc particle word. I have not the expressions option for move and whrite this you whrite.
You know solution ?
Thanks

"RE-ENTER the Postion to "0", even if there is a "0" in Producer -> Radius X, Y ,Z. This will reduce the Particle to a small line like in the tutorial."
-i actually did this step 2 or 3 times while adjusting Birth Rate and Birth Size until the particle looked like the tutorial.
now if I could just change the color of the 3D Particle Stroke cuz it's coming up PURE BLACK!!!?
After analyzing the video over and over, i can't get a thin result playing with the death size and birth size.
i have done many of your tutorials, really amazing,
but this is the only one that i can't seem get to work so far, the only thing i can think of is that something has changed in the most recent version of particle world, what do you think?

thanks! really cool tutorials here ... the only problem with this, is that, because the solid layer is not 3D, you cannot have it cast a shadow ... that's a shame, any other way i could have a shadow from the moving particles onto the floor?

Excellent tutorial as always.
I'm a buyer! I'm a buyer!
Hope you reply, thank you.
I've been doing your tutorials to learn after effects, and I have to say that you are the best teacher online that I have ever witnessed accross all programs.
I have a small problem with this one though. I can get it to work every single time when I do this by itself, I can't get it to work on existing projects.
Do the calculations have to be different for PAL/DV screen sizes? The particle is still connected although it moves only extremely slightly.
Calculations problem?
Hillarious!!!
I like your comments better than the tutorials. of course that u have know how of what u teach, we can see that 10 thousand miles away, but your comments, man makes me crack.
keep doing this awesome work, and whenever I get the chance I will telling about my friends and people that I know in the industry about your marvelous work.
From Brazil, USA, and much more, here is Mario .
Have a good one.

i enjoy your stuff a lot .

Cheers and thanks so far for your tutorials
Nice Demo
it was a very great tutorial
thx.
Now if anyone wants the camera to follow the particle from a distance you can do the following.
Create a new expression at the camera position and add this:
x = thisComp.layer("NullObject").transform.position[0];
y = thisComp.layer("NullObject").transform.position[1];
z = thisComp.layer("NullObject").transform.position[2]-800;
[x,y,z]
Where at z the "-800" is the distance you want it to be from the particle and "NullObject" is obviously the NullObject which the particle follows.

By the way how/where do i get more of those presets?

This is my second day to learn AE. And I got a great tutorial from you.
I am Asian, your words is easy to be understood. the explanation is so clear.
i hope i can be a pro like you in motion graphic.
Thanks for sharing
Si te sale ese error es porque tienes el objeto null no-puesto en 3d
but is deare a way to make that graphic that goes around the letters like in the sport chanel?
like a circle that goes around or like a line goes around
if you know please tell me thanks
michael...
thanks from India...
