Guest Links
To invite a guest, you can invite a user via their email, or send them a guest link to that space. Guest links also include guest codes for users that have already downloaded Cavrnus.

How does Cavrnus work with both Unity and Unreal Engine?

The Cavrnus Platform empowers creators with metaverse solutions that leverage the Cavrnus SDK for both Unity and Unreal Engine pipelines. Our Unity-based native applications and Cavrnus Metaverse Connector™ plugin for Unreal Engine are both core to the Cavrnus Platform and allow you to create metaverse destinations with multi-person co-presence, voice, video streaming and screen share, persistence, collaboration tools, dynamic content insertion including 3D objects, images, movies, sounds, PDFs and much more.

If you create with Unity, you can download the Cavrnus SDK to import the Cavrnus Unity Package which works directly in the Unity editor and allows seamless and easy .holo exports to our Unity-based native applications. Unity creators can utilize the Cavrnus Unity Package to create instant shareable metaverse experiences with their existing work in Unity. With the Cavrnus Unity Package, creators can export properties, particles and avatars to import into Cavrnus.

If you create with Unreal Engine, you can use the Cavrnus Metaverse Connector plugin to instantly add the Cavrnus Platform feature set to any existing Unreal Engine project. Dropping the connector into a project also enables Cavrnus inherent enterprise-grade security, Identity and Access Management (IdAM), along with user access controls and content management features that enable any enterprise, brand or creator to deliver immersive Internet experiences to any audience, anywhere in the world, at scale.

How do I get my Microphone, Video and Speakers to work in Cavrnus?

When you are collaborating and communicating via Cavrnus, we recommend using headphones and avoiding external speaker outputs as these can lead to echoing and poor audio quality experiences. If you are connecting for the first time through our Unity-based native applications, you will need to allow permissions for your device to access your Microphone and Camera. Once you do, you can navigate to your Settings menu to set or modify your Audio Input, Audio Output and Muted by Default settings. If you are connecting for the first time through our 2D web video conferencing client, you will have to allow your Web Browser access to your Microphone.

How do I share my screen?

If you are connecting for the first time through our Unity-based native applications, you will need to allow permissions for your device to access your Screen Recording. Once you do, you can open the Presentation Menu in the upper right hand corner of the Navigation. From this menu, you can start screen sharing by selecting a display source. Others can view your screenshare by clicking your picture in the user list to open up the stream or they can view your stream on any streamboard or surface in the space. Note: if you are using macOS for screensharing functionality, the application will need to be restarted in order for this update to process.

How do I enable AR on iOS and Android tablets?
