🔌Unity
We're excited to release version 3.0 of our Unity plugin! This version builds on the new features introduced in v2.0 and extends support for our latest hardware line-up - the Go, the 16" Spatial Display, and the 32" Spatial Display. We're excited for you to try out! If you have any issues, feature requests, or general feedback, please post on our Discord.
Requirements
Unity 2021+ required.
Looking Glass Bridge v2.0.9 or newer
A Windows machine with dedicated graphics card
An Apple Silicon Mac
Windows computers with discrete graphics cards like an RTX 3070 are strongly recommended.
No support for the HDRP.
Feature Overview Video
This video was created for v2.0.0-alpha of the plugin and some things have changed in v3.0+.
Features
Run interactive scenes from within the Unity editor and in packages builds
Record holograms from the Unity editor
Use hardware buttons for Looking Glass devices (Windows only)
Custom fork of the post-processing stack for holograms
3D cursor and orbit controls for holographic interactions
New in 2.0+
Depthiness Slider
We've added a new "depthiness" slider to the Looking Glass camera setup. You can now adjust the depth of your scene without changing other settings like the field of view or focus.
Camera Transform Mode
We've made an additional Hologram Camera "Transform Mode" that makes it behave much mroe like a conventional camera, called "Camera." In this mode, the pivot will shift to be centered on the position of the central perspective (rather than the center of the volume) and the focal plane can be moved/animated.
Holographic Cameras Creation Improvements
You can now turn normal Unity cameras into Looking Glass camera objects by right clicking them and selecting "Looking Glass" -> "Convert to Hologram Camera."
Quilt Capture Improvements
We've completely revamped the way to capture quilt images and videos. You can now take screenshots directly from the UI using the screenshot button on the Quilt Capture component.
Blocks Integration
Want to share your holograms on the internet? We've got you. We've added a blocks.glass integration directly to the Unity Plugin. You can go straight from the Unity editor to an uploaded hologram.
Hologram Preview
You can now preview Holograms directly in the unity editor without a Looking Glass Display connected, just like viewing blocks on blocks.glass.
URP support (beta)
Run interactive applications and record content from scenes built in the Universal Render Pipeline (URP). Currently no support for post-processing or the 3D cursor.
Render Stacking
You can now use quilts as background elements for your scenes, allowing you to "stack" holograms into multiple layers.
Force Display Index
We have added a toggle to override our logic that forces the Looking Glass window onto the Looking Glass display in builds. This improves setups with two monitors that use raycasting and UI events on a 2D display.
Running Mac Builds
Mac builds got a major improvement in v2.0.8 of the plugin, but still have UX issues. In particular, builds will resize and change position for a few seconds before correctly rendering on the Looking Glass device.
Running Linux Builds
This is not fully tested in v2.0+ of the plugin.
Beginning with version 1.3.0 of the Unity plugin, we have experimental support for Linux (Ubuntu).
However, due to some complications around Unity's window management system, when running builds on Linux it's necessary to launch them from the command line with the "-adapter" parameter set to the index of your Looking Glass display, as in the following example:
YourApp.x86_64 -adapter 2
The above sets your app to run on your second display, which, typically, is the index of your Looking Glass.
Additionally, in version 1.4.0+ of the plugin, there is no support for video recording with Linux. There is a missing dependency to enable this, FFmpeg, which we are aiming to include for Linux users in the future.

Design Guidelines
Building experiences for the Looking Glass can be challenging because it's such a new medium. To make sure your demos really pop, take a look at our Design Guidelines.
