Updating Orbbec SDK from 2.0.18 to 2.1.1

Hi guys. I was using SDK version 2.0.18 previously for body tracking application. Right now when i update to new SDK version 2.1.1, I can’t find the old scripts. Can anyone guide me on how to use the body tracking in the new SDK?

I would like to know what happened to the PoseUser script from previous SDKs? Im working with Body Tracking with Avatar. Please help.
