Custom Trait Generator

Make your very own Sims 4 trait! No S4S, no Mod Constructor, no downloads. You do it right in your browser and walk away with a real, working mod.

Name it. Write it. Give it your own icon. Download it. That's it 🌸

And it's not just Sim traits β€” you can make lot traits too 🏑 Give your church, your cafΓ© or your cozy little cottage its own trait, and it shows up when you're editing the lot.

How it works:
1. Choose what you're making β€” a Sim trait or a Lot trait
2. Type your trait name
3. Write what it says in game
4. Choose who can have it β€” child, teen, adult, all ages
5. Upload your icon (don't worry about the size, generator will adjust)
6. Hit generate and your .package downloads

What makes it special:
β€’ Base Game Compatible β€” no packs needed
β€’ Live preview so you see exactly how it'll look before you make it
β€’ Drop the file straight into your Mods folder and it's in Create-a-Sim

How many you get each month:
🌸 The Community (free) β€” 1 trait
🌹 Rosebuds β€” 2 traits
πŸ’° Motherlode β€” 3 traits
🎨 cas.fulleditmode β€” 6 traits
⚑️ testingcheats true β€” 6 traits

Yes, free members get one every single month. I wanted everyone to be able to make something that's truly theirs πŸ’—

Make yours here πŸ‘‰ traits.nimalusims.com

Whatever you create, tag me so I can see it β€” I genuinely want to know what traits you come up with πŸ™πŸŒΈ

You are able also able to retrieve your old traits if you accidently refresh/ lose your trait.

I also wanted to ask if you can also put something where the sim gets moodlets for the type of trait we gave them cause the trait is just in CAS, and in-game it's not really there

Hello, I just joined and I have a idea for a trait that I want. The only issue is that I tried to connect using Patreon, but I am still stuck on the same screen. I tried another browser and the same thing happened there too.

Hey, it takes about 30 seconds to connect to Patreon to verify you, I’m looking into it to see if it’s quicker but I can’t control the time it takes to connect. Try to log in to Patreon first, and then create

So when updates happen, does this also update the trait, or would we have to remake the trait again

Nimalu Sims Β· July 28, 2026

I’m going to look into this πŸ˜€, I’ll set up a button to update it to the latest patch

It's stuck on the Connect Patreon page for me no matter how much I refresh or sign in and out after clicking Allow πŸ’”

please try again, make sure you let it sign in to patreon, it takes a about 30 seconds

Is this just for looks in your game? Or does it actually make your sim behave according to the trait you create?

R

I'm wondering this too

O.M.G... No you didn't create a simpler way to create our very own traits without the headache and frustrations that I get from not knowing coding nor what I am doing when watching so many other modders videos showing how to mod but the video feels rushed because of editing purposes. I nearly choked off of my water when I read what you created in my email. I wanted to know, does this work for lot traits as well? I would like to make some as well as CAS traits for my gameplays? I need to upgrade my membership because 1 trait is not enough for me and the anticipation for the next month to come will k!ll me softly inside lol.
