What is Graphics Tools?

MRTK Graphics Tools for Unity is a Unity engine package with code, shaders, assets, and samples created to help improve the visual fidelity of mixed reality applications while staying within performance budgets.

Getting started with Graphics Tools

Graphics Tools is normally ingested as a Unity package. To import Graphics Tools into your Unity project follow the below steps:

Note

The Graphics Tools package requires Unity 2021.3 and above.

1. Open your Unity project and select Window > Package Manager from the file menu bar

2. Click the '+' icon within the Package Manager and select "Add package from git URL..."

   

3. Paste https://github.com/microsoft/MixedReality-GraphicsTools-Unity.git?path=/com.microsoft.mrtk.graphicstools.unity#v0.4.0 into the text field and click "Add"

   

4. Graphics Tools will now be installed within your Unity project as an immutable package within the project's Packages folder named MRTK Graphics Tools.

It is advised you use a specific release of the Graphics Tools package to ensure your project is locked to a stable release. Release version 0.4.0 is suggested in step three above. You can also pull another version, specific branch, or git commit hash by altering the URL as demonstrated below:

Syntax	URL example
Specific version	https://github.com/microsoft/MixedReality-GraphicsTools-Unity.git?path=/com.microsoft.mrtk.graphicstools.unity#vX.Y.Z
Specific branch	https://github.com/microsoft/MixedReality-GraphicsTools-Unity.git?path=/com.microsoft.mrtk.graphicstools.unity#my_branch
Git commit hash	https://github.com/microsoft/MixedReality-GraphicsTools-Unity.git?path=/com.microsoft.mrtk.graphicstools.unity#badc0ffee0ddf00ddead10cc8badf00d1badb002

Updating the package samples

Samples exist under the Samples~ subfolder as outlined by Unity's sample recommendations. The '~' character prevents the Samples~ folder for being imported by Unity.

If you wish to contribute changes to the samples you must make a temporary local change to the Unity project's directory structure.

1. Open the GraphicsToolsUnityProject in Unity. The Samples folder will not be visible in the MRTK Graphics Tools package by default. To show the samples select Window > Graphics Tools > Show Samples from the file menu bar.
2. Make any desired changes to the samples.
3. Important: When finished and before committing your changes, remember to hide the samples. Select Window > Graphics Tools > Hide Samples from the file menu bar.
