Auto Nails
by deadlystingnyc
Sims in vanilla Sims 4 don't spawn with fingernails or toenails EVER. Once you notice it, you can't unnotice it. Auto Nails fixes that quietly in the background, automatically applying tone-matched natural nails to any Sim that doesn't have them, across every outfit slot.
Why You Need This
Nail-less hands are one of those small things that quietly undermine an otherwise polished save. You've got beautifully dressed Sims, carefully curated townies, a world that looks exactly how you want it — and then you zoom in and everyone has the hands of a mannequin. Auto Nails handles it automatically so you never have to think about it again.
How It Works
Click any Sim and run Auto Nails → Build Nails Config to scan the nail catalog and apply tone-matched natural nails to all loaded Sims. Once the catalog is built, the mod runs automatically on every Sim spawn — any Sim missing nails on an outfit slot gets short neutral-toned fingernails and neutral toenails matched to their skintone. Outfits that already have nails assigned are never touched.
What's excluded:
- Newborn and Infant Sims have no nail options in the game and are skipped automatically
- Sims with fantasy skintones — aliens and occults with non-natural coloring are skipped entirely
- Bathing outfits are never modified
Nail data persists across zone transitions. You only need to run Build Nails Config again after reloading a save or installing new nail CC.
⚠️ Fantasy skintone matching is not supported in v1. Sims with fantasy skintones are skipped to avoid mismatched results. This is planned for a future update.
Click Menu Options
In addition to the automatic background behavior, Auto Nails adds the following pie menu interactions to every Sim:
| Option |
What It Does |
| Change Fingernails |
Randomizes fingernails from the full nail catalog, filtered for age, gender, occult, and current outfit category |
| Change Toenails |
Randomizes toenails from the full nail catalog, filtered for age, gender, occult, and current outfit category |
| Apply Natural Nails |
Re-applies the tone-matched natural nail to the targeted Sim immediately |
| Enable / Disable CC Nails |
Toggles whether CC nails are included in randomization and auto-apply |
| Build Nails Config |
Scans the catalog and applies tone-matched natural nails to all loaded Sims (not visible if catalog exists) |
Requirements
- The Sims 4 — base game only, no packs required
Installation
- Download and unzip
deadlystingnyc_auto_nails_v1.1.zip
- Drop the unzipped folder into your Mods folder:
Documents/Electronic Arts/The Sims 4/Mods/
- In-game, go to Game Options → Other and make sure Script Mods are enabled
- Click any Sim and run Auto Nails → Build Nails Config to finish setup
⚠️ Both the .ts4script and .package files are required. The mod will not work if either is missing.
Configuration
Create deadlystingnyc_auto_nails.cfg in your Mods folder alongside the .ts4script to override default behavior:
FIX_NPCS=1 ← 1 = auto-apply on spawn to all Sims, 0 = disable
ALLOW_CC=0 ← 1 = include CC nails, 0 = exclude (default)
CC nails are off by default to keep results predictable.
⚠️ CC nails may produce unexpected results. The mod relies on correct tagging to match nails to skintones, but CC creators don't always tag their swatches accurately. If you enable CC nails, results may vary.
Troubleshooting
Open the cheat console with Ctrl+Shift+C, enter testingcheats true, then use:
| Command |
What It Does |
an_state |
Show current config and nail catalog size |
an_fix |
Re-run auto-apply on all loaded Sims |
an_scan |
Rebuild nail catalog from scratch |
an_log |
Write a full diagnostic snapshot to an_log.txt in your Sims 4 documents folder |
Nails not appearing? Make sure you've run Build Nails Config first — the mod won't apply nails until the catalog has been built.
