![]() ![]() If you drag the pick-whip for the expression to the audio keyframe property you'll get an opacity that bounces all over the place like crazy, so we're going to have to do a bit more to it. Then set an expression on your opacity channel. ![]() ThisComp.layer("layerName2").transform. 1 Answer Sorted by: 2 The easiest way to do this is to use an expression. ThisComp.layer("layerName").transform.opacity=50 header or with Group Opacity enabled, this might cause ghost expression errors to occur. For example, write 'one' expression to a null layer that would change the opacity on all the comps layers based on a current point in time. Sometimes AE throws an error unrelated to Workflower and then. It doesnt seem that there is any way to do this in AE. ![]() For example, when working with actionscript in flash/flex, you could set up 'event listeners' for one object, then when that event is triggered, you can instruct numerous objects to react to that one event. I want to use an expression that would randomly bring the opacity of this layer from 0 to 100 and back down, in order to simulate blinking. I started to experiment with expressions, and it seems that communication between layers and other expressions is pretty limited. Adobe After Effects Expressions Opacity ON/OFF expression Posted by Sregier on Jat 5:25 pm I have an animated character that has a separate layer for eyes closed in order to blink. Have a quick question - I'm coming from a flash/actionscript programming background and am fairly new to AE. ![]()
