| Article Focus: In this tutorial, Emanuel Eriksson uses masks and Particle Playground in After Effects to demonstrate how to blow a text, or any object for that matter, off the screen as if it was made up by small grains of sand. |

Create a new composition 320x240, 4 sec. Name it "Text". Create a new solid. Apply Effect>Text>Basic Text. Set Size to 40. You should now have something similar to this:
Create a new composition the same size and length as the previous, call it "wind".
Create another new composition, the same length as the other two. Name it "Sand". Drag in "Text" then "Wind". Then create an Adjustment layer. And finally another copy of "Text".
Apply Effect>Simulation>Particle Playground to the bottom "Text" layer. Open the Cannon pulldown. Open the Layer Exploder pulldown. Open the Gravity pulldown. Open the Repel pulldown.
Now set a keyframe for Radius of New Particles at 0 and another at :5 value 0. Set this layer's in point to -5. Note: If you plan to test your mask and do a lot of previews set the Radius of New Particles to a higher number and move the hold keyframe to frame 2. If you don't, render times just might drive you insane. Turn off Visibility for Wind and set its in point to :5. Add Effect>Blur and Sharpen>Fast Blur to Adjustment layer 1. Then set the layer's TrkMat to Luma Inverted Matte "Text". Set 1.Text's opacity to 65% and set the out point to 1:15.
Particle Playground is always very render intensive to use, but if you keep the amount of particles down to a minimum and keep the particle size as large as possible while testing, render time will be reasonable. ---Emanuel Erikkson ### |
