June 11, 2025
Supported headset models: XR-4 Series, XR-3, VR-3, and Varjo Aero
This release introduces Masking in Varjo Base, possibility to export and import a Varjo Base configuration file, and the new Applications panel.
Note: All listed items concern the XR-4 Series only unless otherwise mentioned.
Masking in Varjo Base
This feature brings the ability to load blend control masks to Varjo Base. Blend control masks have earlier been available only via Varjo native APIs. You can load masks that you have configured in Varjo Lab Tools to Varjo Base. The benefits of loading masks to Varjo Base are that it significantly improves the masks' performance and you don't need to have additional applications running. Read more about Masking in Varjo Base.
Export and import a Varjo Base configuration file
This feature allows you to configure settings and apply them to Varjo Base on multiple computers or switch between different sets of settings on your device. Export settings to generate a Varjo Base configuration file with the current set of Varjo Base settings and Import settings to apply a set already configured settings. Read more about how to Export and import Varjo Base settings.
Applications panel
The new Applications panel feature was added to Varjo Workspace. In the panel, you can see your recently used and pinned virtual and mixed reality applications and start them directly from your headset. Read more about Using Applications panel.
