For each element in your 2D, 3D or 360 environment, you can:
hide or show an element in the editor
use the "Trigger Action" panel to make them appear during the experience.
1. Every media (2D or 3D) can be hidden in the editor by clicking on "Hide".
2. You can hide or show elements using another element with the "Actions" panel. Just add a new hotspot and use the "Show/Hide" option.
Example: Rock, Paper, Scissors mini game
Note: this option works for the presenters and for the learners.
