Making grass with particular, and 3d tracking
on May 1, 2005 at 5:52:50 pm

I've got 2 questions about Trapcode particular.
First of all, is it possible to create tall grass with it, like you would see out in a field? Having the grass gently blowing in the wind would be nice too, but is not required. If so could someone help explain what I would need to do to achieve this?

Next, some of the videos on the trapcode site say that a 3d tracker was used in the creation of them. What sort of software would have a good 3d tracker in it to use along with particular?

For beautiful tall grass blowing in the wind , check out that preset in Particle Illusion at wondertouch.com.

Yes, I'm aware of the grass preset for Particle Illusion, but I am working in a 3d composition and it needs to look like you are walking through a field of grass, which I don't believe can be achieved with the 2d output of Particle Illusion, so I was wondering if I could make 3d grass with Particular.

I've uploaded some preset to my website which I was going to offer for free anyways with my next big update (once I get the pages ready in a few more years *giggle*). It should give you some idea on how you might do it. If you need the impression of the grasss being pushed aside just use the radial field. Be warned, doing such things is a render hog!!!

Thanks, but the link seems to give a 404 error. :(

Hmmm... I'm having some trouble getting this to work when applied to my own layers.
Here's what I'm doing, maybe you can spot some step I'm missing or something.

1. I open up your project and select the particular effect and save it as a preset.
2. I open up my own project, where a 3d ground layer is already positioned.
3. I create a solid layer, and apply the particular preset to it.
4. I go to the settings for the effect, and set the emitter as a layer emitter, and choose my ground layer for it.
5. A light is automatically placed into my project.
6. After effects will sit around for a while like its rendering the frame, but when it finishes there is no grass on the ground.

Maybe your proportions are different? Try to adjust a few parameters and see if it makes any difference.
