Ok so i know servos cant have babies without cheats. But if i use the tombstone of life and death to make my sim pregnant with a servo as the father, will the baby glitch/not have a face/mess up my game or something like that? Or will it just look like the mom?
I read somewhere awhile ago that if you don't have a default replacement of the servo, that if you were to "humanize" the servo it would have the heart shaped face template(face template 1). So theoretically yes it could be possible for the servo to pass on the facial characteristic of the face template but no it will be completely human. I think even in sims having a female give birth a a hulking metal baby would be to much for people.
I once made Marla Biggs pregnant with a Servo through a Tombstone of L&D. The result is, a normal baby boy. I'm not sure if it's an exact clone though. Marla has green eyes, but their son has brown eyes.
There's been nothing to suggest that a baby with a servo father will be a clone of the mother. It's "self" pregnancies that do that. With the servo, it's likely the game draws the servo's genetics from a CAS template in the same way it does with other NPCs that don't have their own genetics, like Grim.
