Hello
I am a beginner. Sorry, but my English is not good either.

# Creating your First Unity Project using Nuitrack SDK

In this very first tutorial, you'll learn how to create a basic Unity project using Nuitrack SDK. As a result, you'll get a simple app with an option of skeleton detection and tracking, which can be modified into a full-fledged VR app.

You can find the finished project in **Nuitrack SDK**: **Unity 3D → NuitrackSDK.unitypackage → Tutorials → First Project**

## Setting up the Environment

1. As a first step, download and install Nuitrack following our [installation instructions](Install.md). 
2. Download Unity [from the official website](https://unity3d.com/get-unity/download).

_**Note**: To ensure stable operation of a project, we recommend you to use Unity 2017.4 or higher for Windows and Linux projects and Unity 2017.4 for Android projects._

3.  Create a new project.

I saw this and made my first project.

I’ve heard that Nuitrack can recognize up to 6 people.
However, only 1 person can be recognized in the project I created now.

I don’t need a rigged avatar.
I don’t even need to draw on Canvas.

I need to print multiple skeletons in 3D space.
I need to recognize multiple people in the first project created and output multiple skeletons to Sphere prefab.

I think it can be made by modifying the script called NativeAvatar.

What should I do? Do you have any reference?
Thank you very much.

Hello @MJS
Look this tutorial: link
2d skeletons are used here, small improvements will be needed for 3d (about working with 3d points https://www.youtube.com/watch?v=F1Vx_pu9dbk&t=2s&ab_channel=3DiViCompany )
Also check out other tutorials on our Youtube channel https://www.youtube.com/3divi_company

To display several 3D skeletons, use the prefab NuitrackSDK/Avatar/3D Avatar/Prefabs/SkeletonAvatar.prefab.
Disable the Use current user tracker option and set the User ID for this skeleton. As soon as the user with the specified ID appears in the frame, the skeleton will immediately come to life!
