![]() Rotate your layers so that they fit with the perspective of the scene. TL DR copy and paste the above expression on the drop shadow effect’s direction property. Start adding your text, making it into 3D layers by checking the 3D box on each text layer. Put it all together and you get this rather ugly looking thing: radiansToDegrees(Math.atan2(toCompVec(), toCompVec())) ![]() Next in the Effects and Presets panel type in (Track) and then you will see 3D Camera Track pop-up. First, make a new comp and drag in your footage file. This is expressed in radians, so to make it useful for the drop-shadow direction control we use radiansToDegrees to turn it into degrees. In the most recent versions of After Effects CC, Camera Tracking has become extremely easy. If the vector you give it is the unit vector along the x axis of the layer (i.e the vector ) the result can be fed into the atan2 function to return the rotation of the layer in relation to the world. So it translates an arbitrary layer vector into comp space. What toCompVec does is to give you the composition equivalent for a given vector on your layer. Using Transform to Create a 3D Effect In order to transform the shadow, we need to break it off into a separate layer. A new high-quality, performance-oriented composition renderer, Mercury 3D, enables this rendering. That’s where the slightly mystifying toCompVec expression comes in. 3D model import in After Effects Beta allows you to import 3D model files in OBJ, GLTF, and GLB format and render them in the same 3D space as native After Effects cameras, lights, and other 3D layers. So we have to find their orientation in comp-space. But for layers that have parents or that are auto-oriented this won’t work. Show drop shadows through transparent layers Make sure the layer meets at least one of the following criteria: Has only fills with less than 100 opacity Has. Simple enough, it compensates for the layer’s rotation by substracting it from the desired value. Note: A Smart Object is a container that can hold one or more layers. Before you can distort them, you need to convert them into a Smart Object so you can work non-destructively. Convert the Shadow Layers into a Smart Object. Normally to keep the drop shadow of a rotating element correctly aligned I use this on the direction property: value - Right away, you’ll see a new list of Drop Shadow layers under the Text layer. Instant crowd scene!īut I want them to have a drop shadow. I have some background elements that I want to wander around, and because I’m lazy I don’t want to hand animate them, so they just have a wiggle expression applied to their position channel and auto-orient switched on.
