Release notes - Hololight Stream 2024.0.0

Discover the features and improvements in the Hololight Stream 2024.0.0 release

New clients

There are now two additional clients supporting two more device types.

  • Lenovo VRX client
    The new Lenovo VRX client features basic streaming, controller input, and controller haptics.
  • Windows client
    The new Windows client allows for streaming to a computer running Windows. The Windows client simulates head pose movement, controller tracking, and hand tracking.

Controller haptics

The new haptics API enables haptic feedback through Hololight Stream so long as the feedback is set up in your application. It works with any Hololight Stream client that provides haptic feedback to the user. Haptic feedback is available for:

  • Meta Quest 2/Pro/3
  • Magic Leap 2
  • Lenovo VRX

Eye-gaze-based interaction

When you activate eye-gaze-based interaction, you can control an application with your eyes. This is available for implementation on the following devices:

  • HoloLens 2
  • Meta Quest Pro
  • Magic Leap 2

Hololight Stream also supports eye tracking in combination with the Mixed Reality Toolkit.

DirectX 12 support

Hololight Stream now supports DirectX 12. To use DirectX 12 in Unity, set it as the supported graphics backend in the Unity “Project Settings”. The minimum Unity version to officially support DirectX 12 is 2022.2.0a17.

NVIDIA RTX support

With the option to use DirectX 12, you can also use real-time ray tracing for photorealistic 3D graphics. To enable ray tracing-based rendering or to upgrade an existing project to use it, follow Unity’s upgrade guide.

Mixed Reality Toolkit 3 support

Hololight Stream now has a new package for Mixed Reality Toolkit 3 (MRTK3). The integration is handled via the Unity Package Manager. We added a guide for upgrading Hololight Stream from MRTK2 to MRTK3 in our documentation.

DNS connection

It is now possible to set up a DNS and use a domain name instead of entering specific IP addresses. Once set up, a DNS connection is possible with all Hololight Stream clients.

Hologram Stability

With the newly added head pose estimation, we’ve minimized the effects of latency resulting in more stable XR content when the client device is in motion.
