Can you advice me on how to attach labels to the parts of 3D model for an educational Augmented Reality mobile application using Unity framework?
Welcome to Github Community Forum !
Log into Unity , once you are in the program itself, there is a lot of tutorial available that will show you how to do it step by step.
There is Unreal Engine also available with tutorials on how to attach labels etc.
Unity vs Unreal = Unity is the winner but Unreal is pretty nice also.
You can request to be in the organisation of Epic Games on Github also.
This program is pretty big and well done, take your time to read tutorials and you will find out.
If anything you can send me a message also.
