hi , so … I have a scene with more than 900 objects with name Mesh obj.001 , obj.002 , obj.003 … and I wanted to change the names to obj_001 , obj_002 , obj_003 … . but if I rename in Blender these names when I import it does not find the Mesh objects , I tried to look in the file * .prefab as HEX but did not succeed , so I was wondering if the rename these mesh in Unity or trough of some other program , to then just import the new FBX already renamed and be recognized , because it would give a lot of work have to get all objects, materials , names, collision and prefab all over again.
Sorry for the English and thank you.
