Unfortunately, there are no Sims3Packs available with this download.
Package files go in your Mods folder. If you are unsure of how to install package files, I refer you to MTS.
These will not overwrite the Maxis defaults.
They do not share EA’s reddish color; they have been separately colored.
As proper freckles you can layer the crap out of them :D [Picture 1 & 2]
The original creator - Jessi-dot - made 36 freckles. I love them all. I plan on converting the rest.
Tip: If you’ve already created a sim and left CAS, but still want to add these freckles 1) Turn ontestingcheatsenabled true 2) Shift-click on the sim you want to freckle 3) Select the option “Edit Sim in Create a Sim”
Lastly, I strongly recommend putting the file Anach_CASDetails8x2 in your mod folder along with the freckles. It’s not required, but with so many freckle choices, CAS will look much better with it installed. (It’s included in the download, but the original’s over here just in case you need.)
