Here’s a reply to an earlier post, two ways.

You don’t really need a solid. Here are two ways, first with an expression and parenting, the second with position separation of Z-depth.

1) Expression, oh boy!

Add you pics to the comp, make them 3D. They should be the same size.

Add this nifty Dan expression to the Opacity of the front (will be on top in the stack) layer (Copy the expression, Alt-Click the Opacity Stopwatch, then Paste, hit Enter):

if (toCompVec([0, 0, 1])[2] > 0 ) value else 0

Make the front (top) layer the Parent of the back (bottom) by pickwhipping from the bottom to the top in the Parent Column.

Rotate the parent pic and you see the backside when it revolves.

Add a camera and the same expression works, so fly-arounds will see the backside of the card.

The expression comes from here:

2) By Z-Depth, back side 1/10 pixel behind

Place the two pics in a camp, make them 3D, P reveals the position, add 0.1 to the Back’s Z,

so the Back would be:

320 , 240 , 0.1

and the Front would remain

320, 240 , 0.0

Now parent the make the Front the Parent of the Back, and animate the Front to control both. The camera works for this too.

If things get a little wonky make sure you’re using the Advanced 3D settings, (Ctrl K>Advanced Setting>Advanced>Rendering Plugin>Advanced 3D).

If you’re using CC Page Turn on a 2D layer (sound like you are not) just choose another layer from the Backside dropdown.

This expression is really worth one’s weight in gold. Maybe diamond, at all.
Had the same problem and found this post … thank you very much!

This expression is amazing! Thank for bringing it to my attention!
One question: The layers with the expressions is in a composition inside a comp that will have the camera. How can I tell the layers to use the camera of the main comp?

Hi, I have used this page turning tool for a long time. It helps me a lot in converting pdf files to flip book.

The page flip effect looks so cool as we are far away from paper books day by day in digital era.
I made page flip books with this tool: https://bit.ly/1ptMgJq

hi how if the front layer is parenting to a null layer?
