Functional Spiral Staircases (with Animations)
For years, Sims 4 builders have stared at empty corners and wished for a space-saving way to connect floors without the clunky footprint of a standard staircase. The wait is finally over. The Functional Spiral Staircases (with Animations) add-on transforms how your Sims navigate vertical spaces, bringing a fully animated, base-game compatible solution that feels like it was always meant to be in the game.
This is not an elevator-style teleport. Your Sims physically climb the spiral, with smooth animations that make every trip between floors feel natural. Whether you are crafting a chic loft, a medieval tower, or a compact city apartment, these stairs are the architectural answer you have been searching for.
What Makes This Mod Stand Out
Created by the talented team behind Project Spiral, this mod is a labor of love. It is a fully custom script mod that does not rely on the game's existing elevator teleporting system. Instead, it uses bespoke animations for Child through Elder life stages, making the experience immersive and delightful to watch. The stairs are also base game compatible, meaning you do not need any expansion packs to enjoy them.
Key Features at a Glance
- Fully animated climbing for Child, Teen, Young Adult, Adult, and Elder Sims.
- Base game compatible and easy to use, just like EA stairs and ladders.
- Auto-applying floor cutouts that move with the stairs when you relocate them in build mode.
- Place multiple stairs directly above each other on different floors for continuous routing to higher levels.
- Includes the Industrial Spiral Staircase mesh by LittleDica and the Radiant staircase converted from The Sims 3.
One of the most impressive technical feats is the floor cutout system. When you place a spiral staircase, the game automatically cuts the necessary hole in the floor above. If you move the stairs, the cutout moves with them. This mirrors the behavior of EA's standard stairs and ladders, saving you from tedious manual adjustments.
Installation and Setup
Getting started is straightforward. To install, download the mod files and extract them to your main Mods folder or one folder deep only, as this is a script mod. After placing the files, it is crucial to clear your localthumbcache before loading the game. This is a standard step whenever adding or removing mods and prevents corrupted cache data from causing issues.
For those who prefer a more streamlined process, the foxygame.net launcher offers a one-click install for Functional Spiral Staircases (with Animations), automatically placing the files in the correct directory and handling version compatibility checks so you can spend less time fiddling with folders and more time building.
How to Use in Build Mode
Once installed, enter Build Mode and search for "spiral" or "staircase" in the catalog, or navigate to Appliances > Misc. You will find the stairs and a selection of swatches to choose from. Simply place them where you want, and the script handles the rest. Sims will route to them just like any other staircase, even if you move the object after placement.
Current Notes and Known Issues
As this is a beta release, there are a few things to be aware of. The stairs currently support only the shortest wall height visually. However, Sims can still use the stairs to travel between floors even with taller wall heights, though the visual gap may be noticeable. A future update will add additional stair heights to match different wall configurations.
Toddlers do not have animations yet and will teleport unless carried by an adult. Pets also lack animations and will not teleport, but that feature is planned for a future update. There are some very minor "snapping" on the legs when Sims enter or exit the stairs, which the team is actively improving.
Important Bug to Know
Deleting the spiral staircase leaves behind the floor cutout, which you must delete manually. The team is investigating a way to automate this removal. Additionally, due to an EA bug with floor cutouts, spiral staircases leading into basements will show a white void instead of the basement below. This is not something the mod can fix, as it affects even the glass dance floors in the base game.
For creators interested in making custom spiral stairs, the team recommends cloning one of the existing spiral stairs and importing your meshes and textures as normal, keeping the general shape of the entrance and exit in line with the rig and cutout. Custom cutouts are not currently possible due to the script's architecture, but solutions are being investigated.
Mod Compatibility and Performance
This is a fully custom mod with no known conflicts. It should not interfere with any other mods in your game. The script has been updated for patch 1.121.342 and includes PlumbBuddy support, ensuring stability for the latest version of The Sims 4. You can safely use it in your main saves without worrying about game-breaking bugs.
If you want to keep this add-on effortlessly up to date with future game patches, the foxygame.net launcher tracks new releases for Functional Spiral Staircases (with Animations) and provides automatic updates, so you always have the latest fixes and features without needing to manually check for new versions.
