Particular depth of field issue
on Mar 11, 2010 at 10:52:32 pm

So i am using Trapcode Particular and just to generate some basic particles in a simple composition.

I want to rack my focus on my camera layer, so that when I do so, the focus will shift from one particle to the next, blurring the particles out of focus that are not at the cameras focus distance at a given time.

It sounds simple enough, but I a cannot seem to get it to work. All of the particles in the comp stay in focus throughout the duration of the camera's focus rack animation.

I must be missing something very simple but I do not know what.

The default for Particular is to use the Camera depth of field settings. So if you have the dof turned on under the camera settings, you should see some depth change in the particles.

Try this, turn your camera aperture settings up to 500 pixels and turn the blur to 800%. There is nothing magic about these settings, but they will tell you if your dof is working and help you dial your focus distance in.

Also, make sure your camera layer extends the full length of you comp. You might have had the layer selected and accidentaly adjusted the layer position or length.

Best,

Mike

i tried those setting and still it will not rack focus.
i also put in a simple sphere, using CC Sphere as a test and the sphere is definitely being affected but the camera, but the particles around it are not.

What version of After Effects and Particular are you using?

If found the problem, Mike.

I was using a type of particle that dose not support depth of field and I had no idea.
I knew that it was something simple like that, just didn't know what.

Thanks for the ideas, though!

Let me guess, you were using a glow sphere. These things happen.

Best,

Mike

Hi there,
I'm having a similar issue with Form. I can't get DOF to work.
As far as the camera is concerned, DOF works on any standard 3D layer in the same comp, but not on Form.
I've tried a few different sprite types, but no luck yet.
Shading from comp lights is working fine.
All the other camera transform controls work fine wth form.
It's almost like I need to enable DOF inside Form.
I'm on a mac
AE version CC 2105
Form V2.1.0

any ideas?

thanks

Check that Form > Rendering > Render Mode is one with DOF.

thanks. Yeah, I've done all the obvious things like that. It seems buggy. I've worked around it.. deadlines to close.

thanks anyway.
