# Setting up your Development Environment

## 1) Installs and Downloads

The Looking Glass Unity Plugin requires:

* Unity v2021 or later
* Looking Glass Bridge v2.0.9 or later

This plugin is compatible with:

* Windows 10 or 11
* Mac with Apple Silicon

{% hint style="warning" %}
For best performance, we recommend Windows laptops with dedicated graphics cards, ideally an RTX 3070 or better.
{% endhint %}

This plugin supports:

* Built-in Render Pipeline
* Universal Render Pipeline (though there are known issues with deferred rendering and the 3D cursor)

Once your Looking Glass is [connected to your computer](https://lfdocs.lookingglassfactory.com/software/looking-glass-bridge), you'll want to download the Plugin:

## 2) Display Settings

In order to see your Unity Scene with a live, real-time preview on your Looking Glass, it will need to be configured with your computer as an extended display, not a mirrored one.

### For Mac

Open your system preferences and go to display settings and ensure "Mirror Displays" is off.

It is also recommended that you set your Mission Control preferences so that "Displays have separate Spaces" is toggled on. This will allow Unity builds to target *only* your Looking Glass monitor, leaving your main monitor free to use normally.

### For Windows

Open your display settings. Select **Extend these displays** from the **Multiple displays** pulldown.

Also, ensure that **Change the size of text, apps, and other items** is set to 100% and that the resolution of the second display matches the following:

* **1440 x 2560** for the Looking Glass Go
* **1536 x 2048** for the Looking Glass Portrait
* **3840 x 2160** for the Looking Glass 16" Spatial Display (landscape)
* **2160 x 3840** for the Looking Glass 16" Spatial Display (portrait)
* **7680 x 4320** for the Looking Glass 32" Spatial Display (landscape)
* **4320 x 7680** for the Looking Glass 32" Spatial Display (portrait)
* **7680 x 4320** for the 65" Looking Glass

{% hint style="warning" %}
For the 16" Spatial Display (portrait) and the 32" Spatial Display (portrait), you need to additionally set the "Display orientation" to be "Portrait (flipped)".
{% endhint %}

* **1440 x 2560** for the Looking Glass Go
* **1536 x 2048** for the Looking Glass Portrait
* **3840 x 2160** for the Looking Glass 16" Spatial Display (landscape)

## 3) Importing the Looking Glass Plugin into Unity

Open Unity Hub and click **"New project"** on the top right side of the window to start a new project.

Title the project and make sure that "3D Core" or "3D (URP) Core" is selected. Select the **Create project** button at the bottom right.

## 4) Cast a Hologram to your Device

With you Looking Glass display connected, open the scene located at `Assets/LookingGlass/Basic Example.unity`

To cast the hologram to the display:

1. Select the “Hologram Camera” object in the scene hierarchy
2. In the inspector, scroll down and select “Cast to Looking Glass (CTRL + E)”

If you see the example scene in your display, your environment is set up properly. If not, please visit our [additional support page](https://lfdocs.lookingglassfactory.com/software/index/additional-support).
