Change face
 

A crazy idea.
Is posible with a any software upload your photo face and change it by the kapintanleutnant at inside u-boat ?

Excusme my english grammar

Si, es posible editar el rostro de la tripulación y ponerle cualquier foto que tu quieras, pero como la foto se va a acoplar al modelo 3D de la cabeza, al final tendrá un aspecto bastante distinto de la persona de la foto original.

Translated:

Yes it is possible to edit the faces of the crew and put whatever picture you want BUT since the picture will later be extended over the 3D model head, it might look very different from the person in the original picture.
