I think this type of content perfectly demonstrates something that could inspire the Create a Zoi (CAS) system in inZOI.
The creator isn’t just making bikinis—they’re adding skin details that tell a story. These small details make every character feel more unique, realistic, and lived-in.
Some features that could work really well in inZOI include:
-
Natural tan lines that gradually appear depending on the clothing your Zoi wears while spending time in the sun.
-
Sunburns with different levels of intensity based on sun exposure and whether sunscreen was applied.
-
Sunscreen overlays, showing visible sunscreen before it is absorbed or washed away.
-
Gradual tanning, where skin tone changes naturally over several days instead of instantly.
-
Different tan patterns created by bikinis, swimsuits, tank tops, watches, rings, sunglasses, and other accessories.
-
Peeling skin after a severe sunburn.
-
Slight redness after spending a long day at the beach or outdoors.
-
Skin-tone adaptive effects, so tanning and sunburn look natural on every skin tone.
-
Temporary and permanent options, allowing these details to either fade naturally over time or be added manually in CAS as cosmetic details for storytelling.
The ideal approach would be to give players two different ways to use these features:
-
Manually add them in Create a Zoi (CAS) to create a specific story or look.
-
Let them appear dynamically through gameplay as a natural result of your Zoi’s lifestyle, such as spending time at the beach, swimming, hiking, exercising outdoors, or working under the sun.
I think details like these fit perfectly with the philosophy of a life simulation game because they allow a character’s appearance to evolve naturally based on how they live, rather than remaining completely static. Small details like these can make every Zoi feel more personal, immersive, and unique.
Natural Body (Zoi / CAZ)
A look like:
realistic human
calm / melancholic vibe
more natural and cinematic
Chest Avoid (stiffness (don’t make a “perfect sphere”)
A slight natural sag looks more realistic
Stomach
Waist
More natural belly button
Hips / torso
Muscles / definition
Exemple: Skin style (“Sims 3 melancholic”)
Soft texture, not too high-definition
Matte or semi-matte finish
Low shine (avoid “wet” look)
Slightly cool/desaturated tones
Soft shadows on face and body
Small natural imperfections (very important)
