![]() ![]() TL DR copy and paste the above expression on the drop shadow effect’s direction property. Put it all together and you get this rather ugly looking thing: radiansToDegrees(Math.atan2(toCompVec(), toCompVec())) You may have guessed that drop-shadow () works a little differently here. This is expressed in radians, so to make it useful for the drop-shadow direction control we use radiansToDegrees to turn it into degrees. Shadows stack on top of one another, in the order they are declared where the top shadow is the first one in the list. 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. Ive tried Save As to a jpg but that didn. Everything else in the image and text is there but the drop shadow effect is not showing up when I export. When I export to a jpg, the drop shadow disappears. Im applying a drop shadow effect to the text. So it translates an arbitrary layer vector into comp space. Hi there - Ive got an image that Im putting some text over in photoshop. What toCompVec does is to give you the composition equivalent for a given vector on your layer. That’s where the slightly mystifying toCompVec expression comes in. Are you still looking for a long shadow tutorial in after effects, well, you made a good decision here, watch this video and insert some nice looking shadow. So we have to find their orientation in comp-space. There are two primary ways to apply a Drop Shadow - through EFFECTS/PERSPECTIVE or through LAYER/. But for layers that have parents or that are auto-oriented this won’t work. This After Effects Studio discussion explores Drop Shadows. Drop Shadow is the basic part of Adobe After Effects software. Simple enough, it compensates for the layer’s rotation by substracting it from the desired value. Introduction to Drop Shadow in After Effects. Normally to keep the drop shadow of a rotating element correctly aligned I use this on the direction property: value. ![]() 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. ![]()
