I'm trying to create a grid of objects, where each object in the grid changes periodically at random. Currently, I have a precomp that contains my object source layers, and I'm using a slider control expression to randomly toggle the opacity of the layers in the precomp. I then have that precomp duplicated many times in the parent comp to create the grid. However, with this method, all of the objects in the grid change in unison. Now, I can sequence the precomp layers to offset the random changing, however this still produces the same sequence of change for each object in the grid, just offset a little in time. I'm hoping to find a solution that truly makes the object change sequence random for each object in the grid. Is there any way to automate this?
Every source layer in the Layers Source pre-comp has an opacity expression: s=comp("Ross Attempt").layer("Layer Control").effect("Layer Selector")("Slider").value;
(Math.round(s)==index) ? 100 : 0
which links to the slider control in the parent comp, which has an expression on the slider: seedRandom(Math.floor(time*4), timeless=true);
random(1,8); //8 because I have 8 source layers in my precomp
