Please look at the Azure Kinect Examples for Unity asset, as well. It works with Azure Kinect sensors (aka Kinect-for-Azure, K4A), as well as with Kinect-v2 sensors (aka Kinect-for-Xbox-One).
The avatar-demo scenes show how to utilize Kinect-controlled avatars in your scenes, gesture-demos – how to use the programmatic or visual gestures, fitting room demos – how to create your own dressing room, overlay demos – how to overlay body parts with virtual objects, etc. You can find short descriptions of all demo-scenes in the K2-asset online documentation.
This package works with Kinect-v2 sensors (aka Kinect for Xbox One) and Kinect-v1 sensors (aka Kinect for Xbox 360). It can be used with all versions of Unity – Free, Plus & Pro.
Free for education:
The package is free for academic use. If you are a student, lecturer or academic researcher, please e-mail me to get the K2-asset directly from me.
One request:
Please don’t share this package or its demo scenes in source form with others, or as part of public repositories, without my explicit consent.
Customer support:
* First, please check if you can find the answer you’re looking for on the Tips, tricks and examples page, as well as on K2-asset Online Documentation page. See also the comments below the articles here, or in the Unity forums. If it is not there, you may contact me, but please don’t do it on weekends or holidays.

How to run the demo scenes:
1. (Kinect-v2) Download and install Kinect for Windows SDK v2.0. The download link is below.
2. (Kinect-v2) If you want to use Kinect speech recognition, download and install the Speech Platform Runtime, as well as EN-US (and other needed) language packs. The download links are below.
3. (Nuitrack-Deprecated) If you want to work with Nuitrack body tracking SDK, please look at this tip.
4. Import this package into new Unity project.
5. Open ‘File / Build settings’ and switch to ‘PC, Mac & Linux Standalone’. The target platform should be ‘Windows’ and architecture – ‘Intel 64-bit’.
6. Make sure that ‘Direct3D11’ is the first option in the ‘Auto Graphics API for Windows’-list setting, in ‘Player Settings / Other Settings / Rendering’.
7. Open and run a demo scene of your choice, from a subfolder of ‘K2Examples/KinectDemos’-folder. Short descriptions of all demo scenes are available here.
* Kinect for Windows SDK v2.0 (Windows-only) can be found here.
* MS Speech Platform Runtime v11 can be downloaded here. Please install both x86 and x64 versions, to be on the safe side.
* Kinect for Windows SDK 2.0 language packs can be downloaded here. The language codes are listed here.
Documentation:
* The online documentation of the K2-asset is available here and as a pdf-file, as well.
Downloads:
* The official release of the ‘Kinect v2 with MS-SDK’ is available at Unity Asset Store. All updates are free of charge.
Troubleshooting:
* If you get errors like ‘Texture2D’ does not contain a definition for ‘LoadImage’ or ‘Texture2D’ does not contain a definition for ‘EncodeToJPG’, please open the Package Maneger, select ‘Built-in packages’ and enable ‘Image conversion’ and ‘Physics 2D’ packages.
* If you get compilation errors like “Type `System.IO.FileInfo’ does not contain a definition for `Length’”, you need to set the build platform to ‘Windows standalone’. For more information look at this tip.
* If the Unity editor crashes, when you start demo-scenes with face-tracking components, please look at this workaround tip.
* If the demo scene reports errors or remains in ‘Waiting for users’-state, make sure you have installed Kinect SDK 2.0, the other needed components, and check if the sensor is connected.
* Here is a link to the project’s Unity forum: http://forum.unity3d.com/threads/kinect-v2-with-ms-sdk.260106/
* Many Kinect-related tips, tricks and examples are available here.
* The official online documentation of the K2-asset is available here.
Known Issues:
* If you get compilation errors, like “Type `System.IO.FileInfo’ does not contain a definition for `Length‘“, open the project’s Build-Settings (menu File / Build Settings) and make sure that ‘PC, Mac & Linux Standalone’ is selected as ‘Platform’ on the left. On the right side, ‘Windows’ must be the ‘Target platform’, and ‘x86’ or ‘x86_64’ – the ‘Architecture’. If Windows Standalone was not the default platform, do these changes and then click on ‘Switch Platform’-button, to set the new build platform. If the Windows Standalone platform is not installed at all, run UnityDownloadAssistant again, then select and install the ‘Windows Build Support’-component.
* If you experience Unity crashes, when you start the Avatar-demos, Face-tracking-demos or Fitting-room-demos, this is probably due to a known bug in the Kinect face-tracking subsystem. In this case, first try to update the NVidia drivers on your machine to their latest version from NVidia website. If this doesn’t help and the Unity editor still crashes, please disable or remove the FacetrackingManager-component of KinectController-game object. This will provide a quick workaround for many demo-scenes. The Face-tracking component and demos will still not work, of course.
* Unity 5.1.0 and 5.1.1 introduced an issue, which causes some of the shaders in the K2-asset to stop working. They worked fine in 5.0.0 and 5.0.1 though. The issue is best visible, if you run the background-removal-demo. In case you use Unity 5.1.0 or 5.1.1, the scene doesn’t show any users over the background image. The workaround is to update to Unity 5.1.2 or later. The shader issue was fixed there.
* If you update an existing project to K2-asset v2.18 or later, you may get various syntax errors in the console, like this one: “error CS1502: The best overloaded method match for `Microsoft.Kinect.VisualGestureBuilder.VisualGestureBuilderFrameSource.Create(Windows.Kinect.KinectSensor, ulong)’ has some invalid arguments”. This may be caused by the moved ‘Standard Assets’-folder from Assets-folder to Assets/K2Examples-folder, due to the latest Asset store requirements. The workaround is to delete the ‘Assets/Standard Assets’-folder. Be careful though. ‘Assets/Standard Assets’-folder may contain scripts and files from other imported packages, too. In this case, see what files and folders the ‘K2Examples/Standard Assets’-folder contains, and delete only those files and folders from ‘Assets/Standard Assets’, to prevent duplications.
* If you want to release a Windows 32 build of your project, please download this library (for Kinect-v2) and/or this library (for Kinect-v1), and put them into K2Examples/Resources-folder of your project. These 32-bit libraries are stripped out of the latest releases of K2-asset, in order to reduce its package size.
What’s New in Version 2.22.x:
1. Added ‘Dont destroy across scenes’-setting to KM (by default KM is destroyable now).
2. Added OnUserAdded & OnUserRemoved-events to the KinectManager-component.
3. Added IsInitFailed()-method to KM, to provide information if the sensor initialization has failed.
4. Removed KinectDataServer & KinectDataClient-scripts and scenes, to avoid deprecation errors.
5. Fixed AvatarController repositioning issue for some models, when ‘Apply muscle limits’ is utilized.
6. Fixed and improved the feet detection in AvatarController, when ‘Grounded feet’ is utilized.
7. Fixed scene restart in KM, to prevent endless waiting for sensor start-up.
8. Upgraded the K2-asset to Unity 2021.3.0f1.
9. (2.22.1) Updated AvatarController to better handle muscle limits and offset nodes.
10. (2.22.1) Added ‘Keep last pose’-setting to AvatarController, to keep the avatar pose after the user gets lost.
