Nuitrack SDK Unreal Engine

Hi,
I would like to set multiple users in a depth camera in unreal project, but I cannot found the tutorial in anywhere.
Would you please me to help how to set up for this?

Thanks.

Could you tell us in more detail what you are trying to achieve?

If you are trying to track two people, then it is tracked without any problems. If you need more, then you need to change the parameter Skeletonization->activeUsers in the config (C:\Program Files\Nuitrack\nuitrack\nuitrack\data\nuitrack.config) for the required number (up to 6 people are supported)

You can check result on “SkeletonJoints” level (also change “Skeleton Visualisation Count” on “skeleton” blueprint)

Thanks for the reply, and there is one more thing I want to know.
Is there any way to show like two different skeleton?
The example uses BP_Joint that are the same on every joint.
I wonder if it could be changed on every joint like head_joint, hand_joint whatever.
Moreover, multi users can be different from another or not.

I watched the video from the youtube (https://www.youtube.com/watch?v=AUnS3h1_L9M&list=PLc9vKgwNtKxUXB8DAwWxBLYBb295RUtqC&index=3)

I hope there would be the way. Thanks in advance.

Sure. Based on this sample, you can make your own blueprint where you can use any object for any joint of any user. (perhaps the easiest way is to replace the joint object with the corresponding array of objects)
