Tutorial Tuesday:  Creating Organic Particles using Trapcode Form

Aug 19, 2014 at 11:49 AM

Inspired by the practical effects used in the Semi-Permanent Sydney 2014 title, Claude Autret explained to Red Giant’s Aharon Rabinowitz how he attempted to remake some of the effects in After Effects using Trapcode Form.

MK12, a design and filmmaking collective with acclaim in both commercial and artistic arenas, created the title sequence for Semi-Permanent's Sydney 2014 conference.  Using chalk, compressed air, and high speed camera's, MK12 created a beautiful, organic, and softly explosive (if that's even a term) effect.  

Check out this nice Breakdown of how it was done, by The Art of Film. 

 

Claude Autret was inspired by the video and wanted to see if he could recreate the same effect in After effects, using Trapcode Form from Red Giant.

Red Giant's Aharon Rabinowitz, was impressed with Claude's remake and recently chatted with him about how he acheived the effect, as well a little about himself.

Claude states "I’m a 26 years old french graphic designer living in Rennes, and have been a freelancer mainly in motion design for about two years now. I discovered motion design a bit by accident when I was working in an agency, and since then I’ve been learning as much as possible, until I finally felt I was able to work in that field. I love to experiment with plugins that extend the possibilities of After Effects like Trapcode ones.

A few weeks ago, I found some interesting effects while playing with Trapcode Form, but had no practical use for them at the time. Then I saw MK12’s titles for Semi-Permanent on Art of the Title, and thought those ultra slow-motion explosions of chalk were the perfect way to test the realism and the control I could achieve on this kind of effects.


So I’m basically using a letter (or a letter converted to a shape, to use only the outside stroke) as a layer map for Form, with really small particles, and then animate the displacement and dispersion so it explodes towards the camera.  I used 3 lights around the form, and shadowlets only, as global shading was too strong for this project."

"One of the tricks that makes it look good is using a high aperture on the camera, so everything closer than the letter gets blurry and creates that powder effect.
You can control the variations with the complexity, octave multiplier and so on. Adding just a little bit of flow also brings some life to it.


I then duplicated the layer map and made it 3D, tweaked the visibility of Form so the particles appear “through” the letter, and used Form as an alpha inverted map, so it doesn’t overlay over the letter. I had used a pretty large ( 960x960px ) composition for the explosions, so I could scale it down and have even smaller details and particles. Each exploding letter was finally rendered as a .mov with rgb+alpha. I’ve seen a lot of people asking about render time, well it took about half an hour for each letter on my not-so-powerful laptop, so it’s reasonable for almost 20 millions particles !


Then it’s just a basic 3D comp with lots of tweaks and color corrections, and a small camera move.
There’s also a part where particles are seen from the side, but that is way easier so I’ll just leave the small video breakdown here:"

"Thanks to MK12 for the inspiration, Trapcode for the awesome plugin, and Aharon for asking me to write this."
