I made a web page based on this tutorial：
But now there is a problem, I do not want to roll every page, for example, my first page on the second page you want this effect, the next is like a normal rolling.
What I’m thinking about is adding a keyframe for a jump scene on a timeline:
This result is really can jump to the next page, but the effect is not good, because it is easy to wear. And I do not know how to get it back to the last scene now. So I would like to ask if there is no better way to solve this problem.And I found that there is a problem, that is, when the first page, whether you are rolling up or down, you can jump to the second page.
