Object Occlusion

Hello! I am not sure if Nuitrack can do this or even where to start looking for coding, if Nuitrack can do some object occlusion. Much like ARKit shown here: https://www.youtube.com/watch?v=vkS-VqAss4s

I was thinking originally maybe a point cloud, with a occluding type shader, but the point cloud doesn’t match up with the skeleton (also its a huge performance hit.)
