    I realize you can trigger keyframes with markers, but in this case I want to be able to trigger them when a slider value reaches a certain number.

    So basically, I have a layer with a slider, and the starting keyframe value is 0 and the end value is 100. Then I have a number of layers that I want to start playing their 2 position keyframes based on the percent finished of the slider value, so they slide in one after the other. Then if I adjust the slider’s end keyframe, all of those layers start time will adjust accordingly. Doing this with markers would be wayyyy too time-consuming for this project.

    Well I can see why no one jumped to help with this… I figured it out, but it ended up being pretty complicated. Probably not as complicated for someone better at math and coding, though.
