In this case, I can use lookAt to make the glow always look at the camera.Īccording to the Help, it says you must define a fromPoint and atPoint. ‘thisComp’ Expressions in After Effects revolve entirely on manipulating values inside an object hierarchy. The return value can be used as an expression for the Orientation property, making the z axis of the layer point at atPoint.''īasically, lookAt makes a layer FACE another layer. The argument atPoint is the point in world space you want to point the layer at. The argument fromPoint is the location in world space of the layer you want to orient. '' Argument type: fromPoint and atPoint are Arrays. So, I went into the Using AE PDF and searched an expression I had heard of once but never gotten around to using: lookAt. In this case, we are using posterizeTime() and the wiggle expression together to create a poor mans stop motion effect.
It's may be something unlikely to happen (and some keyframing could probably fix it), but I dread how every time I change my camera move I'd have to change those keyframes. The Quick Answer to Using the Wiggle Expression in After Effects Find the layer property you wish to wiggle. Ordinarily, it should at least follow the object even slightly, at least.
