At the moment it’s two C++ classes and a blueprint. One class which exposes access to the Kinect and an Actor derived class which maps that into a UE4 skeleton data format. I then have a Class blueprint based on that Actor class, which I’ve added my skeleton mesh asset to and every tick the blueprint calls into my Actor class to extract and map the data from the Kinect onto the skeleton to update the joint orientations. It’s still very much a prototype, I’ll tidy it up more and make it robust when I get some time.
