Refer to the Key attributes and methods (expression reference) Here I would recommend avoiding this as the keyframes are basically referenced as an index, so things can get messed up if you add one ahead of a keyframe you were already using - def incorporate some error handling. Returns the start time of the layer, in seconds. If you utilize the start time overrides you can pull this from: Returns the Out point of the layer, in seconds. Returns the In point of the layer, in seconds. Regarding the next part where you want the expressions to activate based on other compositions, I recommend using the in-out Point expression. Part 2: Start/End based on other layers within pre-comps: Just select it in the Essential-Graphics dropdown. That also means no nulls, adjustment layers, etc.Īs an added bonus, if you use the essential graphics panel, you can put all the controllers in one pre-comp, but have the controls available no matter which comp you are in. What this means is that you will need to create yourĮxpression link utilizing a pre-Comp. ![]() More In-depth Answer: Adobe's Docs - Skip to the Layer Sub-objects partĪs I understand the Adobe documentation, only Layers can be accessed, To reference Effect-Controllers between compositions, follow the below formula: comp("ComName").layer("LayerWithExpression").effect("EffectControlerName")("EffectControllerType") Simply replace "thisComp" with "comp("ComName")" Part 1: Reference other layers in pre-Comps Thank you all ye "overflowing Stackers" who contribute! :) Heck, help me figure this out and perhaps I will make a tutorial. It could be used for a MULTITUDE of amazing effects and could save a ton of time for everyone. This would be an OUTSTANDING tutorial and I believe it would be very popular if someone did it. It would be awesome if there was a method out there to achieve this effect. We do something like this in Flash using Actionscript all the time. Wouldn't it be awesome to trigger or call it from one one layer when you wanted it from one expressions layer? Why not just paste a comp in the spot you want it to play every time you want such action? Well in after effects if you wanted a "blink comp" to play 40 times in two minutes you would have to create 40 layers, or pate the key frames on that comp 40 times. IT WOULD BE AMAZING IF somehow we could trigger other comps to begin, repeat, stop, maybe reverse, and do this all from one Main Comp using an expression layer. Blinking, Walking, Flying, Look Left and Right etc. At certain points I would like to add triggers to call frequently used comps that contain actions like. Ideally: I would like to create an " Expressions layer" in the main comp to TRIGGER other comps to play. Is this possible? (Sidenote: A random blink through entire movie would be nice) but I still want to know how to do this for the reasons below. (and other actions, explained below) Rather than "re posting" the comp or key frames movements every time I want a blink or a particular action, I want to create a script where I can trigger the Blink comp to play. I want animate a the blinking of a cartoon character. Control AE timelines using ONE EXPRESSION LAYER ( much like using Actionscript) to trigger frequently used comps such as blinking, walking, flying etc.
