change object with animation?

Hello unity3D.I have a question about changing game-objects.How can i make it that i can change the gameobject from one mesh to another?For example.I have a ball and i want to change it into a rocket using unity3D animator in like 5 frames and then change the game-object to a bomb in 10 frames.If anyone know how i can do this.Can you please tell me how?

Don’t think it’s possible in unity. I know there are assets that can modify meshes but not sure if one exists that will convert from one mesh to another over x amount of time. Look on the asset store though, someone might have made one.

It might be possible to do this in external tools like blender and have intermediate stages have their own prefab that you swap out. Expensive in terms of the number of gameobjects being held in memory.
