              I use mesh.setParent Mesh | Babylon.js Documentation (babylonjs.com)  to make the child mesh move position and rotation with the parent mesh.
Playground example:
Examples | Babylon.js Playground (babylonjs.com )](https://playground.babylonjs.com/#7V0Y1I#1627 )
             
            
              
            
           
          
            
            
              use .parent = instead of setParent() this way the current position won t be impacted.

              I just tried, it is still the same problem, I need one mesh always be attached with another mesh
             
            
              
            
           
          
            
            
              Can you repro in the playground ? I am not sure to understand your issue

              I updated a very simple playground example, hope it helps to better understand
             
            
              
            
           
          
            
            
              Not sure what you expect to happen, this seems to be what you want https://playground.babylonjs.com/#7V0Y1I#1629
