Inserting TC Particular or Form in to 3D Tracked Scene (CS6)
on Sep 28, 2012 at 6:31:17 pm

Hello,

I've been watching some of the recent CS6 tracker tutorials and it works fantastic but I have not figured out or do not understand how you get a particular "cloud" of particles to stay in place/tracked.

In this scene I am including, I had just a little blob of particles created in TC Form and a Particular particle stream that just did some little circles and as the camera moves, they just sort of move out of place.

Does anyone know the procedure or can you make a short tutorial on this?

Thanks,
Eric

Michael,

Not sure if you have gotten around to seeing this yet but I made some progress based on that note from last year and using the light emitter position. The TC Particles seem to stay in place well but the first part has a weird look and I can't quite grasp what is wrong. Maybe it will make sense to you.

TC Particular in 3D Scene



I was not able to figure out the same with TC Form however since it does not appear to have the same feature with tying to an emitter light. Appreciate any help.

Thanks,
Eric

Hello All,

Do we no longer have anyone on the Trapcode forum?

Yes, I am here. I have been really busy the last couple of weeks. What exactly is your problem. Can you describe it and send me the scene perhaps.

Michael,

That's funny, I could swear I saw a different post on my phone referencing a "image based grunge" on my scene but the comment is gone now. I do have an optical flare on the first part but also on the second. So, problem 1, since you noticed the odd grunge, I was wondering how I get rid of that.

It is a particle cloud with an optical flare in middle. I tracks quite well so that problem is just why I am getting the weird glare.

The second question is (now that I've figured out most of how to track particles using the emitter you mentioned long ago) is how to do the same using TC Form.

I did not see a similar capability to use a light as an emitter.

So, essentially, I can't figure out how to track a TC Form particle object.

Thanks ahead and sorry you are so busy....or maybe that is good.

typically the grunge image is an image that optical flares uses as a lens effect to give realistic grunge to the shot. In your case, it doesnt work because it looks like a fractal. I would use a different preset and see if it is still a problem. I did post another reply to your video. You can probably still see it there. As for form, I am not sure. I rarely use that particular plugin. I will fire up afx and see what gives. I have a tracked scene I can test with.

I am busy. 3 jobs and 4 kids. Enough to drive you crazy or to drinking, lol

Just checked and form works fine with the scene. Not sure what the problem is. Can you upload the scene or email it to me?

Hey Michael,

Three jobs and 4 kids?! Wow. Is the COW one of the 3? lol

I appreciate your time.

On TC Form - I figured it would work for you. It is the procedure that I need I guess. As I mentioned earlier, I didn't see the same method as I used for particular where you tie it to an emitter in the particle settings.

So, in short, how do you attach Form to a null or whatever? lol

Thanks!

No, the cow is not a job, it is my way of trying to give back to the community. Truth be told, I am a board certified attorney with my own practice, a software developer with a company and an independant freelance motion graphics artist...with 4 kids under the age of 9. Needless to say, I am busy. Now, on to your question.

The way you control form is through the baseform emitter position. If you need to move this, it is a little cumbersome to do altering the xy and z sliders, so I usually picwip them to a 3d null and animate the null instead. Hopefully, this will solve your problem.

Hey Michael,

I very much appreciate you squeezing this in today! I'm sure this will fix my problem.

On a good note, I hope you noticed how well those items were all tracked using the CS6 tracker.

The shark and Jaws logo didn't budge!

Thanks again.

Hello Again,

Just wanted to update on that grunge problem from my earlier post with the particle cloud on the sidewalk. I removed the Optical Flare which helped a little and it now looks like this:







Still not right but from what I am hearing it could be applying 2D effects to it. The only thing else applied is roughen edges so I am thinking that might be the problem.

In any case, i will be trying the TC Form along with that.

roughen edges is the problem i am sure. It uses a fractal to create the effect which depends on the screen coordinates. Take that off and you should be ok. If you need it, precompose it and then put it in and set the layer to face the camera.

Michael,

That did seem to fix it. I didn't really need the roughen edges, was just playing with settings and it looked cool. Not so cool with it after all though.

I'm still having some problem with using a null and TC Form though.

I made a small form object, made the null as a 3D layer, and while it moves the form object, it seems to move the entire frame as well. But more importantly, it doesn't stay put relative to the scene.

Basically, the same scene you see with the particle cloud but I want to place the form object there. It does not appear tied to a tracker null and not sure what step I am missing.


Thanks,
Eric

You misunderstood. I meant actually picwip the emitter position of the form plugin to the postion of the null, not the entire layer. You will have to alt click the stopwatch for the xy position of the form plugin and then picwip it to the null position. Then, alt click the z of the form plugin and then picwip it to just the z position of the null.

Hi Michael,

Thanks for the clarification. Yep. I misunderstood. Will try that tonight!

Thanks again for the help.

Alright, call me an idiot but I'm still missing something.

Here are your instructions: You will have to alt click the stopwatch for the xy position of the form plugin and then picwip it to the null position. Then, alt click the z of the form plugin and then picwip it to just the z position of the null.

The only xy position I see in the form plugin are under "Base form" and "Center XY". That gave me an error so I presume I did it wrong. Past that, I think the z position is self explanatory. [Actually, even the z position is not self explanatory now that I look closer. It is size in z, particles in z, center z, and rotation z).

If it is individual, x, y, z I guess I would understand that but looks like you separated xy and then z for a reason.

Appreciate the help.

Hello Michael,

I'm finally back to this thing again. I keep reading the instructions but Form is a bit confusing. I mean, it doesn't seem to have a z position at all. I can picwip the xy position under Transform/Position but there is no z.

Confusing.

Hello Michael,

I think I got it!

Using the Center xy and Center z seemed to do it. At least for now but I think that was it.
