In the past when I wanted to loop an After effects Composition I always do duplicate the composition multiple times, until this day where I had a this tiny composition to duplicate a hundred time!! After a few research online I wanted to share to simplest way to loop an after effects composition / precomp, so here it is.
Shot 1 – Place the composition you would like to loop in the new composition
Shot2 – Right Click on the Composition Layer – Click Enable Time Remapping
Shot 3 – Once time mapping enable this is what you should see
Shot 4 – Add a script to the time remap
On PC : Hold Alt + Click on Stop watch
On Mac: Option-click stopwatch
Replace timeRemap by this loop expression:
Shot 5- This is where the magic happen! -Click at the end of your composition, drag until the end or where ever you want it.
Click play – Now your After Effects Composition Layer should play in loop!
