i do what you want to do all the time.
you will have to buy Boris Perspective Unit and also get Andy’s FREE Better 3d though….but it’s worth it.
you apply Andys 3d and then Boris perspective BCC Page Turn in that order.
shrink your pics back to 50 in the motion scale tab.
in Andys 3d apply a -6 in Z position.
go back up to motion tab scale and re-scale to suit.
in BCC Page Turn change your Offset to see if the peel doesnt get cut off. if so then adjust Andys 3d and or
the motion tab scale.
with a little diddling you will get it right.
then apply Offset keyframes to each layer.
also run your light and shadow up all the way in BCC Page Turn.
all this is on the same timeline…no nesting crap to deal with.
i did this effect in about 45 seconds.
