Oddly, all references to these methods in the Workspace page have been removed. Searching for “Region3” on the page gives 0 results, and searching for “Ray” on the page highlights a now-dead link.
Using the search bar to search for “Region3” or “Ray” returns results under Workspace, but these links lead to missing pages.
Whenever you try to access any of these methods’ pages, change Workspace to WorldRoot and hit enter. Documentation may not be fully transferred over yet.
The change was noted in Release Notes 410:
A better resolution would be to have these pages redirect to the methods located in the WorldRoot class or to add the WorldRoot pages to the search query, as they do not show when searched.
