I am a Japanese university student.
Currently, we are developing interactive content with Nuitrack.
Is there a way to do motion capture of multiple people in Creating your First Unity Project using Nuitrack SDK?
Yes, you can track skeletons of several users (up to 6). To do this, you have to edit nuitrack.config file (%NUITRACK_HOME%/data): in the section “Skeletonization”, set “ActiveUsers” to the desired value (up to 6 skeletons)
