Using Light as Motion Path for Trapcode Particular

Hi,
I am trying to make an animation for a project, but I cannot figure out some things. I am trying to create the effect that a person is throwing money out the back of a car. I have the live shot of the person in the car, but I cannot get the money to behave how I want it to. I am trying to use the Trapcode Particular, but I can't get the particles to follow any motion path. When I set the settings to motion path, it prompts me to create a light. I create a light, but can't figure out how to make that light have an actual path rather than simply being a spot light. Please help! I'm sorry if I don't make any sense, please ask me to clarify if you need it.

Because you are doing it all wrong! If you wanted to use the Motion Path option in the Air physics model, your light would have to be exactly named like that - Motion Path 01. It's not what you want, though. I'm 100% certain of that. You are looking to create a conventional light emitter, which is a whole different thing. For that, your light should be named Emitter (or whatever other prefix you define in the plug-ins Options/ Settings panel). Then you must set the emitter type to Light. If you use spot lights and want your money to emit directionally, you need to set the emitter to Directional as well. Apart from that, Particular will use the light's color, cone angle and intensity to colorize and eject the particles. After that, you can animate the light in 3D space to whatever you need it to do.

Light as motion path

hurt my hand -- no caps. anyway, i've searched the forums, searched the knowledge base even searched the manual . can't find a how-to on this. it seems to be something everybody takes for granted. is there a tutorial or something...

Actually, "Motion Paths" and light emitters are two completely different things in Particular, so it all depends on what you are trying to achieve. For a classical trail, that fades off after a while, you'd indeed use an emitter (Velocity at zero, Opacity over Life and Color over Life). In that case it is important to match the names. Either make your light's name start with "Emitter" or change whatever is the name match string in the "Options" panel of Particular. Motion Paths on the other hand are available in the Physics section of the plugin under the Air model and require the light to be named "Motion Path", followed by a number. There is no option to change the match string for this.

Tween or Motion path for blank keynote with animated stars?

I create star particle effect from this tutorial: http://www.schoolofflash.com/2008/03/flash-cs3-particle-effect/ and got help from this discussion: http://forums.adobe.com/message/5518425 in order to get what I wanted. My code is:
var starsArray:Array = new Array();
var myTimer:Timer = new Timer(50);
myTimer.addEventListener(TimerEvent.TIMER, addStars);
myTimer.start();
addEventListener(Event.ENTER_FRAME, moveStars);
function addStars(e:TimerEvent):void
          var star:Stars = new Stars();
          star.x = stage.stageWidth / 2;
          star.y = stage.stageHeight / 2;
          star.alpha = Math.random() * .8 + .2;
          star.scaleX = star.scaleY = Math.random() * .8 + .2;
          star.xMovement = Math.random() * 10 - 5;
          star.yMovement = Math.random() * 10 - 5;
          starsArray.push(star);
          addChild(star);
          star.cacheAsBitmap = true;
function moveStars(e:Event):void
          for each (var star:MovieClip in starsArray)
                    star.x += star.xMovement;
                    star.y += star.yMovement;
                    star.alpha -= .01;
                    star.scaleX = star.scaleY -= .01;
                    if (star.scaleX <= 0)
                              kill(star);
function kill(star:MovieClip):void
          starsArray.splice(starsArray.indexOf(star), 1);
          removeChild(star);
However, I wanted to move the star particles around. The problem is that the star isn't on the screen, but is called in the actions in the blank keynote. I don't know what I should do next to get the result. I looked up online for tweens and motion paths but all i see is that they required the star to be right on the screen, I think? I also heard something about the compiled clip but I don't know how I should go about creating one and using it to move around the stars while it's animated with all the actionscript. All I wanted is for the star particles to float around the screen (on a path that I can draw out if possible).....

Each star is created in the addStars function. Its position is set in the first two lines:
     star.x = stage.stageWidth / 2;
     star.y = stage.stageHeight / 2;
So, to move each star to a new location when it appears on the stage, you'll need to change the x and y property values for each star. One simple way to do that is to use that same Math.random() function.
Try changing those first two line to:
          star.x = Math.random() * stage.stageWidth;
          star.y = Math.random() * stage.stageHeight;

Multiple motion paths for my 3 photos

I’ve been trying to use key frames and motion paths to create a particular effect, but am not really getting anywhere.
This is what I’m TRYING to achieve using 3 different photos.
(Step1) Photo 1 appears full screen, zooms out as it reduces in size. Ends up at a position occupying left third of screen.
(Step2) Cut to Photo 2 full screen, does the same thing – zooms out – reduces in size (in the process revealing small Photo 1 on left). Ends up in middle third of screen.
(Step3) Cut to Photo 3 full screen – does the same thing – zooms out – reduces in size (in the process revealing small Photo1 on left and small Photo 2 in middle). Ends up on right hand third of screen.
However, although I have been able to complete these as individual moves on each of the 3 photos, they remain as 3 separate clips in the timeline.
I can never get the small Photo 1 to be revealed under Photo 2 as it zooms out, or in turn the small Photos 1 & 2 to be revealed under Photo 3 as it zooms out. After a day on this, I’m obviously doing it quite wrong. Maybe it can’t be done in FCP5.
Any advice appreciated.

Are you putting them on three different tracks?
Yes, on V1, V2, V3 – but no matter where I put them or how I staggered them in relation to each other, it doesn’t work. Each track totally covers the others up – no “transparency”.
Before I possibly went crazy I decided to start fresh.
First, I trashed all my FCP preferences, double checked everything in FCP, and repaired permissions. In FCP I created a new clean “test” project with just the 3 video tracks as before. I also got a friend a little bit familiar with FCP to watch exactly what I was doing. I re-did the three motion paths. Same 3 photos, same moves in each.
It worked perfectly!
I don’t know what’s happened. My first attempt was obviously quite wrong somewhere. My old G4 has been a bit cantankerous lately with FCP. It's all very weird.
Andy - I’m giving you the points, because you forced me to seriously forget about trying to do a fix - instead, redo the whole thing. I’ve lost a day, but it’s been worth it.

Using URL maps to search for a particular sub-domain in a URL

Hi Guys,
Seem to be having some trouble with URL maps, and trying to search for a particular sub-domain in a URL. Let me explain:
We will have a number of applications frontended by our CSM VIP such as:
sftp.poc.monash.edu.au
callista.poc.monash.edu.au
I'm trying to get the CSM via policies and URL maps, to search for say "callista" and direct this traffic to a particular farm as below...however when i use the match statement the connections are dropped.
map CALLISTA url
match protocol http url *callista*
map CALLISTA-SFTP url
match protocol http url *sftp*
policy CALLISTA
url-map CALLISTA
sticky-group 197
serverfarm CALLISTA
policy CALLISTA-SFTP
url-map CALLISTA-SFTP
sticky-group 198
serverfarm CALLISTA-SFTP
vserver CAL-POC-DECVIP
description decrypt VIP for SERVERFARM CAL-POC
virtual 172.16.11.116 tcp www
persistent rebalance
parse-length 4000
slb-policy CALLISTA
slb-policy CALLISTA-SFTP
inservice
So i'm wondering if there is a better regular expression statement i can use to ensure that all the traffic that has "callista" in the URL is directed to a particular farm?
thanks
Sheldon

Having a read through the CSM config guide I think i may have found the answer. I noticed that the URL maps only work on searching a "path' after the domain e.g. the presence of either "index" or "cep":
callista.poc.monash.edu.au/index.html
or
callista.poc.monash.edu.au/cep/
I've tested the above logic and this holds true....therefore there doesn't seem to be a way of searching for a "subdomain" in the URL as opposed to various bits of a "path". That is i'd like to search for "callista" or "admissions" instead of the path
callista.poc.monash.edu.au
or
admission.poc.monash.edu.au
Can someone confirm this one way or another? And if the sub-domain search is not possible, are there alternatives to getting it to work?!
thanks
Sheldon

How can I remove the 1 million emitter limit for trapcode particular?

Hello everyone, I've recently started playing with trapcode particular v2.2 and can't seem to rise above a problem. My PC setup is: i7 965x, gigabyte ga-ex58-ud3r, ati firegl v8600, 16 GB DDR3 2133Mhz Kingston Beast, 2x1TB WD. I want to use more than 1 million particles and the emitter does allow me to change that number. I've seen tutorials that use more than this and I can't seem to be able to use the correct settings. What must I change??? I would really appreciate your help.
Thanks!

Why use two instances of particular when I should be able to use just one?
How so? If it's not possible it must mean that the plug-in was not designed to work this way...
And I want to do that as less complicated as possible.
But then again, the opposite could be true?! Working with a gigazillion particles could be so unwieldy, it becomes effectively unworkable. Sorry, but I really don't get people's obsession of trying to do everything in one comp on one layer, when a little structured approach with pre-comping and all that stuff may provide a much simpler, more efficient workflow. E.g. in your case why would you even bother with using an emitter that has all particles, when modulating their motion to form your logo would be tricky even in a 3D program, when just the same could be achieved by multiple layers with a lot less particles?

How to extract list of object and formula used in variables as Excel for a particular Webi Report

Hi,
Is it possible to get the list of variables and objects, and variable formula used in a webi report extracted in excel or PDF in BO XI R3.1?
Thanks In Advance,
Shenbu

Hi Shenbaga,
You can try to get this information using the report engine sdks of BusinessObjects which is specific to webi reports.
Please refer to the link to download the dev guide and api referrence for XI 3.1
SAP BusinessObjects BI 3.x and Lower - Developer SDK Library
Refer to the Report Engine Java SDK dev guide and api referrence.
Go through the dev guide in detail and you would be able to use the report engine sdks as per your needs.
Additional Note: There have been changes in report engine sdks from XI 3.1 to BI 4.0 and you would not be able to get all the features available in XI 3.1 report engine sdks in BI 4.0.
Hope this helps.

How can I use a different search path for FlexRIO IO modules?

I want to use an IO module that is outside of the LabVIEW tree, but it seems like LabVIEW only searches in shared/flexrio/IO modules, and I can't figure out how to create symlinks in windows.
Is there a variable I can set somewhere to include other search directories for the IO modules?
//Olof
Solved!
Go to Solution.

Hello Olaf,
There are two locations on your Windows computer that are searched for FlexRIO adapter module support files. The first is the Program Files directory you have indicated in your post; this directory holds the support files for NI manufactured adapter modules. However, there is another directory that can be used for the location of any non-NI manufactured adapter modules. For Windows XP this location is: C:\Documents and Settings\All Users\Documents\National Instruments\FlexRIO\IO Modules. If you are attempting to install support for a non-NI manufactured adapter module, please ensure that you have installed all of the adapter module support files into this folder.
If you would like more information on this as it pertains to a custom adapter module development, please email the support email address listed in your Module Development Kit Manual. This email address will give you direct access to the NI FlexRIO R&D team for support as indicated here. If you want to discuss adding the ability to search other directories for adapter module support (other than the two listed above), please email the MDK support email address.

Is there a way to create an object using Trapcode Form and then use that object as a particle in Trapcode Particular?

I made some objects in Cinema 4D and I tried to import them into After Effects CC 2014. I get an error saying 'Cannot find Adobe Premiere Pro Dynamic Link'. So I tried it in AE CC and that worked. However, I want to create a form object and then use that as a particle for Trapcode Particular. Is this even possible?
Thank you for any help!

There are also size limitations or rather suggestions for particle size. If I were creating an animated 3D shape using Form or C4D and wanted to use it as a particle I would keep the size of the particle about 1/6 to 1/8 of the comp size. You would create a new comp for your particle, animate it, then nest the particle comp in your main comp, turn off visibility, and then use it as a particle in Particular.

How to identify the project in CMOD used for a particular data source

Hi
I had a Business Content Data source which is enhanced with ZZ fields and user exit is written in CMOD.
How can i find in which project used to write the code for that particular data source.....
When i check CMOD i can find nearly 10 to 20 different projects
Thanks

Hi,
One simple way is goto CMOD and give project names with Z* or Y*. First findout the naming convensions following in your project and see.
Then gibe projects one by one and select COMPONENTS option and click on Display, if you find the following Function Exits means it is our DataSource project
EXIT_SAPLRSAP_001
EXIT_SAPLRSAP_002
EXIT_SAPLRSAP_003
EXIT_SAPLRSAP_004
Thanks

Motion Paths In After Effects CS6?

Hello,
I was wondering if you could draw a motion path for objects to follow. I have multiple objects(12) that all need to follow on the same path. Do I have to animate all of them individually, or can I draw a path? These objects are NOT masks. They are text imported from Illustrator(CS6).
If Microsoft Powerpoint can do it, then surely Adobe can...
Thanks,
Jack Reynolds

You can do this in several ways. The easiest is with Parenting. Next would be to tie position of one layer to position of another layer with an expression. You can also draw a mask path on a layer, select the mask in the timeline, reveal the position property of another layer, set a new keyframe for position to guarantee the mask path will be used as a motion path, and paste.
See this thread for details and a screenshot.

These are AE basics. You can also find more information by using the Search Help field at the top right corner of AE.

Drawing a Motion path

Hi fellows!! I would like to ask please, if there's any way which allow me to draw an arbitrary line with the pencil tool for instance, and then tell to flash to use this path as a motion path for an object on the stage by creating a motion tween. I know that this can be achieved by classic tween, but I look for a way to achieve the same effect but by using the new animation model of motion tween. Cheers!! Atar.

Thanks for your response, but I'm already know that I can edit a motion path after it was created. But this process is harder than to draw the desired path with the pencil tool. I look for a way to a priori draw the path as I want.
Cheers!!
Atar.

Multiple motion paths in CS5?

Hi-
I'm new to Flash and have a question. I'm creating a Helium atom for my technology class and am trying to get 2 electrons to circle the nucleus. I've successfully created a classic motion path where one electron circles the nucleus. How do I create another (duplicate) motion path for the other. I'm not sure this can be done, hence the question.
Any suggestions for the newbie would be greatly appreciated.
Thanks,
Mark

Select the frames where your motion path is being placed on, right-click and select "Copy Frames" and paste them on a new layer

Light Streaks - Not Using Trapcode particular

Hi there i am here to as a question .... is it possible to create Light Streaks whiout using the Trapcode Particular from Red Giant ??
Regards ASilva

Well on Programs like blender i don't know how to works with them
And besides i was just asking if it was possible to create something similar to the effect i show on the link or the same without the need to use the Plugin Trapcode.
Or if i can use the particular Pluging that is already on After effects like the "CC particle world" ... (guess that is the correct name).
And if it is possible i would like to know because buying the plguin would be too expensive for my pocket
