The point to look from, the point to look at. 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.

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. Along with quantifying gene expression levels, CAGE can be used to identify tissue. The argument fromPoint is the location in world space of the layer you want to orient. For each track the Y -axis scale corresponds to the number of tags. Since youve only provided one value, AEs Expressions Engine only applies the addition to the first value of the array in this case, the first parameter for scale. Here’s an expression for the Scale property of a layer that maintains the relative size of the layer in frame while changing the z position (depth) of a layer or the Zoom value of a camera: cam thisComp.activeCamera distance length (sub (position, cam.position)) scale distance / cam. How to add an Expression in After Effects Right-click on the layer-property and select Edit Expression Select your layer-property and in the Main Menu go to. '' Argument type: fromPoint and atPoint are Arrays. The problem is that this only adds the +5 to the x axis of the layer, it doesnt seem to do anything to the y axis. So, I went into the Using AE PDF and searched an expression I had heard of once but never gotten around to using: lookAt. 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. Ordinarily, it should at least follow the object even slightly, at least.
