How do I instantiate an object with one of it's children deactivated.

I want to spawn the player with one of the children deactivated by default. How do I do this?

I imagine you could just deactivate it in the editor, project panel pre build. If you need it turned off only on special occasions, then you would only be able to turn it off after instantiate.

I think if u keep a object off in editor mode, then u can not target that object at runtime. So best solution is just target that object in your script. Keep SetActiveRecursively false at start and whenever u require write SetActiveRecursively true.
