246 RESPONSES TO "LIGHT STREAKS"

by Colin 08/28/2010
To Chris, the commenter below, about the sprite issue.

Newer versions of Particular don't have the "custom" option, they instead have the "sprite" option. To complete this tutorial select "sprite", then go down to "texture" and expand the menu. There you will see an option called "layer". Simply select your layer from the drop-down menu and everything should work just fine.
by Garry 08/23/2010
Great Tutorial, but how we do, if we want to put 2 particles/tapes/lines with diferent colors?
by Chris 08/22/2010

Can you create your own lightsource instead using the wiggle?
by Ben 07/20/2010
Hi.
Where is the "Trapcode" in the cs4 version?
And i haven't got the particular effect.
Please help me.
by Drakmour 07/14/2010
In what version of Particular was it made? I don't have Custom shape for particulars in my 2.0, other options don't give such effect as in tutorial, it just put a few images that I made with sticks... (
by Erick 07/08/2010
To change the name 'Emitter' open Trapcode Particular's Option box."

help!

How can I get the colour in the trail but on a white background?

@Henry
Thats cause you didn't buy the program....
by Henry 06/17/2010
Does anyone have a big X on their screen? I thought it was a temp guide thing, but once i render my project the X is still there, any solutions anyone?
by Steve 06/16/2010
Sorry, I'm being a tool. Solved it.

Wasn't on Active Camera View, was on a different view. Meant the Adjustment layer wasn't being previewed. All good now.

Great tutorial - many thanks!
by Steve 06/16/2010
For some reason, I'm not able to use the adjustment layer to add the effects such as colour and glow?

I can make the adjustment layer, add the effects, but they have no consequence on the image. I'm using CS4 with particular v2 on a Mac. Any ideas?
by Carlos 06/10/2010
It's because in Particular 2 it's called Sprite
by Amit 06/09/2010
Thanks For the Tutorial
The Best Tuts I have ever seen in my life
Thanks one more time
by Mèche 06/05/2010
Hey,
how come i don't have the custom particles, for the particle style, in after effects cs5?
anyone?
by jacky 06/03/2010
Awesome Tut! Was wondering if you could specify a path like in the nano ad, like how the light follows the peoples hands? Again, amazing tut, so pretty!
by zsgraefl 05/30/2010

by Namor 05/04/2010
hi andrew,im using cs4 and also the trial trapcode particular.but in particle type i cant use custom,bicouse is not there,what can i do? thank you.keep up the excelent work
by ronald 04/27/2010
man you're great. but i have this problem. i'm using version 2.0 of trapcode particular. i think this version does not have that custom type of particle that's why i can't make a custom shape. what can i do to make my light streaks?
by Zie 04/15/2010
i'm using trapcode 2.0. did as told using sprite > texture etc. the effect isn't the same as the light streaks shown in the tutorial, it's more dispersed.. is there any way i can obtain the light streaks by using trapcode 2.0?
by Jacob 04/03/2010
i have a request/question about the movement of the line that you created, i know that you can make it move randomly, but can you show me/us how to control the movement. i ask this because whenever i try to do this it doesn't curve, and when i try to curve it myself, it doesn't turn out right.
please reply via email
by Jo 04/02/2010
I love that:

"aaah.. sh*t.." at the end :)
by Rita Silva 03/30/2010
Hey Andrew, thanks for this great tutorial!
I want to ask you how to make this effect around a shape like a square.

by rowan 02/26/2010
@dari, you have to motion track your footage and create a null object, and parent the emitter to the null object
by Gerardo 02/20/2010
Beutifull

This tutorial teach me and inspired me a lot
Thank you.

by Dari 02/13/2010
Hey Andrew Nice Tutorial, does anybody know how to make the the stream follow a certain point, such as if you imported a movie of your hand moving it would follow your hand? If anyone knows please answer me
Thanks
by atul chauhan 02/05/2010
hey andrew i saw ur tut, its great. but i want to create a streak of light which goes in z depth and reflects back towards camera to give an illusion that the light streak hit something and reflects back in space. pls answer this
by Takko 01/04/2010
Great tutorial, This works with the FREE particular demo from trapcode.
And for those with 2.0 as said before there is no custom option, you'll have to use sprite, then you can select the layer under texture and you can choose for start at birth - stretch
by aa 01/01/2010
Use sprite, it's the same
by Anish 12/26/2009
i have a little problem. my trapcode-->particular won't let me set a custom particle. I made one but when i go to Particle type or whatever it is it has no 'Custom'. I am using particular version 2.0.1. Thanks for the awesome tutorials Andrew.
by bath mateus 12/18/2009
Very nice posting. Thanks.

by Owen Thomas 12/15/2009
hey jackyrulezs...

Just rename the light "Emitter" after you get the error. It's case sensitive, so capitalize the "E".

If you want to change the name of the emitter go to the options tab at the top of the Particular effects panel. Type in what ever you want and rename your light(s) layer the same.
by someone 12/12/2009
Sorry Gnat but this site is an amazing privilege how the hell could you complain with this much top of the line free knowledge at your finger tips.
by Gnat 12/09/2009
I think you should put a big disclaimer on the tutorial page saying, "you must spend another $300 in order to do this tutorial" because, dude, I already bought your software, and I see all these great tutorials, and I think I can do them, and then I find you have to have another set of software? BOOO!
by Orange Hill 12/07/2009
Fore those of you, using Particular 2:

Particular Type "Custom" is now changed to "Sprite" and the "Custom Layer" you´ll find under "Texture" - Layer...

Greetingz from Berlin.-
by jackyrulezs 12/06/2009

i'm using After EFX cs3 and i follow the tutorial.. but when i change the emitter to light there an error. the error was the trapcode is already used the name emitter and layer name was emitter... i dont really what happened.. please help me....

by gabriel 12/05/2009

by jsutton4 11/05/2009

by not so rich dude 10/31/2009
I don't have particular. Does it come with Ae, because everyone but me seems to have it?
by yubaobao 10/14/2009

by Ian 10/08/2009
What about Trapcode 3D Stroke?
by BlueMoon 10/01/2009
Yo, TrapCode's Particular v2 has no "custom" particle type. However, i found out that "textured polygon" works quite well instead of that... you might wanna add a note to others out there =)

by William 09/11/2009
How come when you talk about bringing the "particle_50" then going to particle type then you have a custom button.....but how come i dont have a custom button?
by Jim 09/07/2009
To Mike.
I think, Instead of alt cllick the stopwatch and making the wiggle(.5,100)
you click the stopwatch and move it around and remember to move through time as well.

Great tutorial, really like it! Thanks!!

ps. At the end, you could say "Keep Winning!" or something.. uuhm.. ds.
by Laxman 09/04/2009
Great tutorial ........ its very useful to every one ........
by Mike 09/02/2009
I don't wanna sound like a noob, but I just watched this and it's great.

But instead of setting it to make its own random movements, how would you go about creating a specific path or movement for the light?

Thanks,
Mike
by Leonardo 08/19/2009
Great turorial, very well explained.

Quick question.

Is there any way that I can use this effect to write a word!?
by Simon 08/10/2009
awesome!do you sleep man?!
by FlorianF 08/10/2009
Here's one way. Let's say your layer with the stroked path is called "Stroke Layer". Copy the mask shape for the path and paste it into the position parameter of your follower layer. This should create keyframes that cause the follower to trace out the path over a 2-second period. Then just add this expression for position to sync it up with the animation of the "End" parameter of the stroke effect:

percent = thisComp.layer("Stroke Layer").effect("Stroke")("End");
valueAtTime(2*percent/100)
by Air1993 08/02/2009
Amazing Tutorial Loved it. Did a litle extra to the cameras and abit of change to the wiggle expression. http://www.youtube.com/watch?v=Njln4KV9t98 anyone want to give so constructive critism to camera work please.

Hola,

hi i need help,sorry but this is the first time i am learning after effect,mine is mac and i can't find the trapcode =(
by Tomer 05/23/2009
This is so irritating,
I did everything Andrew said but you cant see the light at all, you can only see the little two arrows following where the light is but no light. By the way if this helps I have CS4 and when I put the effect on the "Particles" solid and the put the option "light" it says:
"In this mode lights are used as particle emitters. Only lights whose names start with 'Emitter' are used. Creat a light with Layer>New>Light.

To change the name 'Emitter' open Trapcode Particular's Option box."

What do I do?!?!?!?
Plz help

Hi, I whanted to make that effect but i dont have some particules, what to do?
by jean 05/03/2009
super cool
by Ashley Staggs 05/02/2009
for those of you who want to know how to get the emitter to follow a specific path, just create a mask on a solid, then go to mask path, copy it and paste it to the emitter position.

If someone has already said this then sorry
by jessel 04/27/2009
you're so great . i've been watching your tutorials for some time now. thank you thank you so much.

any way, i just wan't to ask if its possible for the light to follow a certain movement? like in the ipod nano commercial? or to follow a text ?
