Remember the tutorial from a previous post back in Dec 2020?:
Do you wonder if there’s a quicker way to do something in Illustrator? There’s a tutorial on there to create the As in illustrator.
I used them to create a very quick and simple animation in After Effects
Import the file you would like to apply the explosion effect to. You don’t need layers.
Select Pixel Poly from the Effects & Presets – tweak the settings how you like.
I made it a sub-comp because I wanted to use Time Remapping and it doesn’t seem to work unless it’s applied to a sub-comp.
Select Time Remapping. This will insert a keyframe at the beginning and end of the composition (mine was 5s long, if I remember correctly) then swap the two keyframes over so that the end position becomes the start and the start becomes the end.
Then it’s up to you to play with the speed, Easy Easing, Graph Editing etc.
Finally, I imported a sound effect called ‘slurp’ from Envato Elements.
Render to format of your choice and done.
