When you create annotations, each one has unique camera position AND target. You can use this to ensure navigation at each annotation is focused on the right spot.
Adjusting multiple annotation positions allows you to manage the camera path between them. Notice how the camera pivots around each individual object and the movement between saved views feels more natural:
You can set the current camera target by double-clicking on the model, and reset it by double-clicking the background. The camera target is preserved when setting an annotation's camera position.
However, because double-clicking also creates an annotation, you need to switch between the Annotation tab and the Scene tab to use the target feature effectively:
Editing Camera Position
Don't forget you can also update an annotation's camera position and target AFTER creating it:
You can add links, images and other formatting with Markdown.
Show/Hide Annotations by Default
There is always the option for Sketchfab users to hide or show all annotations in the bottom section of your model viewer.
However, as the model owner, you can choose the default option (show or hide) in 3D Settings by choosing either Show annotations or Hide annotations in the bottom section of the viewer and clicking Save View in the top-left corner of the viewer.
