Family Genetics With Custom Skins

(1/3) > >>

Simgoose:
Ok so I have asked around about how to make skins with tattoos. and found a couple of tutorials. and think i can work it out.

Now before i get into trying to make my first skin... i had a question.

1. If I create a or 2 Sim through the CAS with a custom tattoo skin (or other)
and have children, what skin will the childen take on?

(I'm using helene's default skin replacements atm, and will use these to create my tattoo skin)
NB: i will only use this for personal use, unless i get approval to share the moded ones.

jsalemi:
That really depends.  Kids can take on the skin of either parent, or some shade inbetween.  The game grades the skins on a major scale of S-1 (very light) to S-4 (very dark).  So if an S-1 and and S-4 have a kid, the kid can be S-1, S-2, S-3, or S-4. If a S-1 and S-2 have a kid, the kid would be either S-1 or S-2.   Two S-2s would only have kids with S-2s.

But it's more subtle than that, too.  Underneath those major scales is a genetic scale from 0 to 9 (or 0.0 to 0.9 -- there's a tutorial/discussion about this somewhere in Peasantry), and each S-x represents a range of the genetic numbers.  So an S-1 could genetically be 0.0 to 0.25 (I'm making up these ranges -- see the tutorial). The default skins all fall in the middle of each range, and if you have no other custom skins in your game, it'll choose one of the defaults.  But using SimPE you can alter the genetics of custom skins so they fall in various parts of the genetic range, and have a much wider selection of potential skins the kids can get.

Simgoose:
Cheers for the reply.
Ill see what i can find in the tutorials.

One more question: If i build a sim with a normal default skin...

then in the game change the skin to a tattoo'd one... this wont affect the genetics... will it?

jsalemi:
No, I don't believe so -- you'd have to edit the sim's package file manually to change the genetics.

Marhis:
If both parents have a custom skin (with genetic value unaltered, i.e. = 0), you have a 50% probability each.

You can, however, modify the genetic value of those custom skins, and they will behave like jsalemi explains in the above post.

It will. I have tested it, and even if it sounds silly, when a baby is born the game will pull the skintone value from the skin the sim is actually showing, and not the value stored in DNA.
I pointed this out here, if you want a longer explaination.
