If I were to need an effect like that, I would probably use a combination of a page curl animation with a lens distortion effect to bend the image with the page.
There might be a better way, that's just off the top of my head.
Yes that would work but,Im talking about an actual shader type effect.Like a page transition with this type of effect.As far as i know this type of shader effect uses vertex shaders ,I don't think Construct can handle vertex shaders.
