2 sided layer in AE
I am trying to rotate a 3d layer in the y axis, and have the back of the layer be a different image. Ive tried precomping 2 layers, Ive also tried parenting the 2 layers and seperating them along the z axis by .5. None of this worked. Please if anyone knows how to do this with an actual edit I would greatly appreciate it.
Thank you

Well if you have card wipe or card dance you can easily create a 2 sided layer. It comes only with professional after effects 6 and up. Otherwise you’re going to have to tweak in 3d space a bit. try offsetting the back image. And if you’ve pre-comped remember to collapse transformations in the main comp. (that tiny * button in the timeline window)

I just used this Expression. Got it from the Dan Ebberts bag of Expression tricks a while back-
Switch off the Back Layer. Apply the following Expression to the Front Layer. Ensure that the Blend effect is applied to the Front Layer. Then apply this expression to the “Blend With Original” parameter
LayerName=effect(“Blend”)(“Blend With Layer”).position;
a = to_world_vec([0,0,1]);
b = LayerName – to_world(anchor_point);
c = dot(a,b)/length(b);
if (c > 0){
0
}else{
100
}HTH
