    Masks with random Opacity

    mattd94212891

      Hello,

       

      I hope someone can help me here.

      I have one Layer in After Effects with like 2000 Masks in it.

       

      Is there a way to animate the Opacity randomly on each Mask without touching every Mask individually, so that every Mask blends in at a different time.

       

      Here is a Picture:

      Every single Point should blend in randomly.

       

       

      Thanks in Advance!!

          You could apply some sort of interpolation expression using linear() and the start and end values being generated randomly. A simple form would be something like that:

           

          seedRandom(4567,true); //random seed, change number for different results

          mRand=random(0,3); //random time in seconds

           

          linear(time,0,mRand,0,100); //interpolation

           

          Otherwise you might get much better control by using your shapes on a shape layer and putting them inside respective groups. Dealing with masks is like pulling teeth in AE. Also consider other techniques liek re-creating the dots with text on paths and using text animators.

            Additional note: You still have to go into each mask opacity property, of course. Your approach is simply not very efficient.

              Thanks alot, Mylenium for your fast answer.

               

              Do you maybe know, if there is a possibility to this with an effect-transition? Like for example the card-blend effect does..

              I'm not really into this expression-stuff

                That example doesn't look very random to me.  I think you need to re-evaluate what you're doing... unless we don't know the totality of what you're doing, of course.

                  Card Dance only works for regular grid, which your artwork is not. Matching the "cars" to your dot pattern would be a pain. As I said, try to trace the paths and then type in a dot character in a text layer, referencing the mask path, then apply opacity text animators and wiggly selectors. Likewise, any number of similar techniques e.g. using the Vegas effect or particle effects may work. Again: Your current approach is simply not ideal. You've jumped ahead too far in teh wrong direction and now hit a snag.

                    Great Idea doing it with text!!!

                     

                    Thank you very much, Sir!
