Can anyone please implement this.
I want the 3d object to not move with the camera in AR setup.
the position of the 3d object should be fixed and it should go out of the frame when we move the webcam.
Hello and welcome to the Babylon community!
We can surely help you implement what you want in terms of maths and API, but unless you make an offer on the Service offers and requests category, we won’t be able to make your entire experience. 
Please keep in mind that, except for the core team, the forum users are volunteers, and even us on the core have our hands full with fixing bugs and implementing new features
