How to make the backside of a layer a solid color??
Is there something you can do to a layer so that when you rotate it to it’s backside, the image on the front of layer doesn’t show through? (image on the front, solid on the back).
I am working on opening a greeting card. Once it’s opened, you can see the image that’s supposed to only be on the front of the card on the inside.
Hopefully you get what I’m saying, Thanks for the help!

im guessing one way you could do this is make another 3d solid layer the color you want it to be and place it ever so slightly in z space behind the layer, precomp it with the card front layer and it should work?

You can do this with sub-pixel positioning. Put a colored layer (black) behind your footage, make both 3D and give the colored layer a position of 0,1. Parent that to your footage.

With sub-pixel positioning and parenting, if your trying to use another color besides Black for the back, somtimes you’ll see a little fringing, so an alternative is below.
Method 2.
Again make the layers 3D, but leave them with the same exact position numbers, parent 2 to 1, and add these Opacity expressions to make the layer invisible when the camera (you need to add a camera) is on it’s backside.
To layer 1.
a = toWorldVec([0,0,1]);
b = thisComp.layer(“Camera 1”).position – toWorld(anchor_point);
c = dot(a,b)/length(b);
if (c > 0) 0 else 100Then this expression on the second layer down:
a = toWorldVec([0,0,1]);
b = thisComp.layer(“Camera 1”).position – toWorld(anchor_point);
c = dot(a,b)/length(b);
if (c < 0) 0 else 100 The only difference between the two is the direction of the > (or) < These are Dan expressions from earlier posts. -
Hi,
A third way would be to split your layer when it reaches a 90 degrees rotation then add the fill effect to the splited part.
Salut.
