Note that if you set the Transition from one of the Push variants to the Page Turn then you'll get smooth swiping. But that's a swipe action and not a continuous scroll.
Scenes are made such that only one can really be shown at a time, so if you're constructing a page that could be sized such that it shows multiple scenes at the same time (a like a long page) then it won't really work. However, there are a few different approaches to achieve the same basic result
- Use Symbols in a single scene, as symbols are basically 'scenes within scenes' anyways
- Use multiple Hype documents and stitch their exports together by copy/pasting their divs all in a single .html file
- Use a timeline that acts as how you want to scroll, and then use some code that binds to it. There's several solutions on the forums if you search. Here's one I found that looks more like individual scenes: Sticky Scroll Effect
