Sims 4 Genetics


If you edit a Sim's face or hair in CAS, does it actually change their genetics, or is it just a makeover? One of my Sims had a child with bright red hair and I have no idea where the hair came from, because both the parents have black hair. I don't play with generations, do they pass their genetic traits to grandchildren? Vlad's kids in my new save have elf ears and I'm wondering where they got them from.

    If you open up things in Sims4Studio you can see how they've been flagged. I am not sure if these are the same flags as used for genetics. It's likely so as when I examine the file's details I've yet to find other ways to determine it.

    But... it's pretty common to find something like hair or clothing where every color swatch has been flagged as the same, even when there are visibly many different swatches.

    It's easy to fix this manually, but obviously becomes very tedious if you have a LOT of CC.

    I do know that the color swatches for clothing DO matter. If you set a like or dislike you can find your sim is upset about wearing brown, when they're decked out in pink on your screen, because your CC maker just clicked to 'paste to all swatches' and so every color is actually seen as brown by the game...
    - This happens ALL THE TIME for me when it comes to furniture being not properly flagged...

    So I'm just guessing the color swatch flags are also used in genetics.

    You can find some of this bad flagging without using Sims4Studio by just filtering CAS by colors or fashion styles and noticing how many wrong things show up or how many right things are missing...

    Since I often build outfits by filtering by color and style to give myself a good look for that sim, this is something I've become keenly aware of.

    Some CC makers are more guilty of this than others...

  • @HillyBeth Those are great photos how did you set them up? Even the three kids are posing so nicely.

    It looks like they only inherit from their parents, not their grandparents. Inheriting from a grandparent would be fun if you got a kid with pointy ears who's grandparent was an elf. But then on the other hand, you wouldn't be able to weed out the feature from the family tree if you didn't like it. It would be nice if we had both options to toggle on or off.
  • I saw what you all mean about the CC. I have been experimenting in CAS and had one kid get a purple ponytail. :joy: It also puts the CC makeup, jewelry and eyelashes on everyone, girls and boys. It would be nice if Maxis would let us tag items ourselves so we can somehow arrange them how we want them in CAS, who we want to wear them, sort our personal favorite clothes, have a little unique closet or jewelry box or something. I would love some sort of CAS sorting tool.

    @HillyBeth I will look for some posing packs! Thank you for mentioning them. :smile: I didn't know there were mods like that.
  • @HillyBeth Wow those Sims are so beautifully made. Are your Sims on the gallery? I never put freckles and other skin details on my Sims, but maybe it really does make them look more realistic.

    I have another question sort of related to genetics if someone could answer I would really appreciate it. What is a preset? I have seen some celebrity Sims that have presets for the downloads. Does that mean the preset is like an artistic rendering of the Sim and not made with the actual genetics in the game? I've always wondered how people got Sims to look exactly like celebrities. I can't barely get my Sims to have nice eyebrows.
  • It's pretty much a 50/50 of features, placement, & colouration. The skintones blend together and can make entirely new skintones. As far as most body & facial features go, it's derived straight from the parents. No generational skips. The elf ears are from Vlad's vampire form, too, btw. Occult Sims have 50/50 options between forms, too, but they get weird.

    There must be something at play with either randomness or recessive genes. In my Diminish the Torment challenge my founder, who I created in CAS, had brown hair. He married Becca Clarke, who also has brown hair. Their son was born with blond hair. I've always wondered where it came from. (I don't have any CC or mods.)


    I've had this happen in my game too. 3 generations of fully black haired Sims (all of them, even the married in ones) and then a baby was born with red hair.

    I had something similar in my game. Ailis Fyres is the only blond child of Dominic (blackbrown) and Moira (red).

    I find that genetics mostly make sense. Only the skintones are a bit off after they introduced the "500 skintones batch" in 3 sections. Previously a child would be close to one parent's skintone, or somewhere between parents. Now there are plenty of sims getting a skin tone outside its parents' range. Might be a bug, or the new system is just not as good.
