After Effects is a great program that packs a lot of punch right out of the box. However as an experienced motion graphic designer you need more than what AE offers off the shelf. When looking to create particle, lighting and film effects it is best to go with a 3rd party plug-in to get the job done quickly and easily. Here is my short list of six powerful plug-ins that any serious After Effects designer should add to their arsenal.
1. Trapcode Particular
Trapcode Particular is one of the most talked about After Effects plug-ins of all time for good reason. Its powerful and easy to use particle system makes it the ideal choice for creating an array of effects like smoke, dust, clouds, grass, bubbles, rain, snow, debris and anything else you can think to throw at it.

2. Video Copilot Optical Flares
In 2009 Video Copilot launched the incredible After Effects plug-in Optical Flares. This affordable add-on creates stunning real life and artistic lens flares. Its ability to track 3D lights make it a truly indispensable tool and “wow” maker.

3. Magic Bullet Looks
Red Giant Software continually produces innovative plug-ins for After Effects users. Magic Bullet Looks is a toolkit for designers to add film moods and effects to their compositions. With over 100 presents and the ability to tweak your own, Red Giant Looks will not disappoint you with its overwhelming number of features.

4. Trapcode Shine
Trapcode Shine is an oldie but a goody. This simple plug-in can breath life into a composition by adding majestic light rays and glorious shine.

5. Trapcode Starglow
Trapcode Starglow is another classic plug-in that everyone should own. Similar to Trapcode Shine, this plug-in can add shinning twinkle and glow to your composition.

6. Lenscare by Frischulft
Although this plug-in is the most obscure one on the list, it does not make it any less important. Lenscare is a remarkable plug-in and is in a class of its own when it comes to blurring effects. With a few simple steps this plug-in creates realistic rack focus blurs. Go check out this plug-in for yourself and get ready to fall in love.

The great folks at Red Giant Software put together a useful resource for motion graphic designers called Red Giant People. Much like the now defunct Trapcode People website, Red Giant People is a place where anyone can submit their own After Effects presets. The library is already off to a good start and is a growing resource of free goodies.
Ever wanted to add some spice to your data being presented in After Effects? Get ready to be blown away by Yanobox‘s new plugin called Nodes for After Effects, Final Cut Pro and Motion. This plugin offers editors and Motion graphics artists a unique tool to combine text and graphics into beautiful 3D animations. Nodes lets you play with a number of different presets, or you can create your own graphic vocabulary by customizing all available parameters.
