What is an Overlay?
An Overlay is the digital content that a user is presented with on the screen of a mobile device when viewing an Aura.
Overlays can include videos, images, 3D scenes, web pages or any combination
thereof. Overlays can appear individually or as part of a group (multiple Overlays and sequenced Auras). Overlays can also be reused multiple times on different Trigger Images.
Each Aura can have up to a whopping 50 Overlays attached to it - meaning you can pack a whole lot of content into a single Aura.
What specifications do Overlays need to meet to be uploaded and delivered to a mobile device successfully?
