Is there Nuitrack Virtual Fitting Room Full Tutorial

I was following 7min Virtual Fitting Room tutorial on youtube

Is there other tutorial that can make the same effect on the last part of the video where 3 clothes changes based on the gesture of the user swipe left? Will it also work for multiple users?

There is no specific tutorial.
You can simply set up several avatars, place them at the same distance from each other, and move them with a swipe gesture

Swipe is described in this part of the tutorial about the gallery
