VIVE Intro
Developing for VIVE is straightforward and in general you can follow the docs of the used Photon product (PUN, Realtime, Bolt & Voice). A few notable exceptions and additional guides are highlighted below.
VIVEPORT
VIVEPORT is the app store for virtual reality content and experiences. It's available in 61 markets and compatible with a range of devices from HTC, other SteamVR devices, as well as devices from partner companies based on the WAVE runtime for all-in-one VR headsets.
With the VIVEPORT SDK, the launched content can check the user's profile and license, implement In App Purchases (IAP), Dowloadable Content (DLC), Stats and Achievements, Leaderboards and more.
VIVEPORT Authentication
Photon supports the authentication of users via the VIVEPORT APIs. This makes sure only verified users can access the online aspects of your game.
Setup and usage of the VIVEPORT Authentication is described in each Photon product's "Authentication" section.
