Be able to use alignment features to create a more immersive experience with Hololight Stream.
Alignment
Alignment in Hololight Stream Client allows users to adjust settings to better align the Hololight Stream experience with the real-world environment.
Alignment on non-Apple devices
Origin
The origin is the point around which the entire space is positioned.
Spatial tracking
Spatial tracking captures the real-world surfaces around the client device. The data from this scan of the environment helps the device find the floor along with other spatial data. XR devices like PICO 4 Ultra, the HTC VIVE devices, and the Meta Quest devices require spatial tracking to be enabled in order to set the Origin.
| Spatial tracking differs between XR devices. This is because the capturing of real-world surfaces is handled by each device on the operating system level. |
Enable spatial tracking
-
Open Hololight Stream Client on your device.
-
Select Alignment.

Select Update to start spatial tracking.
Tracking automatically starts when setting an origin and there aren’t any spatial entities saved.

Some HTC client devices require updating the spatial entities on the device itself. On supported HTC devices, open the System Dashboard, then select Settings > Boundary > Mixed reality > Set up.
