This is great! Can you have a different image or solid color on the back side of the layers that you are bending, like with the Page Turn effect? Or could you precomp two 3D layers to act as the front and back sides and apply the bend to the precomp with the collapse transformations switch turned on?
But I'm working on it
Sorry that did not answer immediately. It was very late '5 am'
But if you have any questions please let me know
