Aliens Being Born As Vampires

Hybrids are very much possible. Go to create-a-sim. Make an occult Sim. Then make another occult Sim and set them as married. If you've got an alien and anything else you get a blue caster, vampire or mermaid. I've had a couple of cases where my teen sim was a caster who could also al use any alien power but creating/altering a disguise.

I found this thread because my current caster/alien mix can be edited in create-a-Sim but it doesn't show while playing. More alien than the mother, who dresses like a human in both guises and has hair.
