Turns a Sim into a vampire
traits.equip_trait trait_OccultVampire
The selected Sim becomes a vampire instantly, with no need to wait for a bite or the transformation.
In The Sims 4 occult Sims come with packs, and each one is stored as a trait. That is why they all open with the same command: traits.equip_trait and the right trait name. Remove the trait and the Sim is human again. Vampires, spellcasters and werewolves also have ranks, and the stats.set_stat command takes them to the top rank in one go. Every code works only if the matching pack is installed.
Most codes here need cheats turned on first. See the section on how to open the console.
