Create New Scroll

Creating a scroll allows the user in an easy way to create credit lists or any other scroll, either vertical, horizontal, with ease points and so on. When creating a scroll from scratch, Viz Trio automatically creates a scroll scene on Viz which the user can redesign.

Note: New scrolls must be created using the scroll function.

This section covers the following topics:
