Fortnite Tools

Tools for taking apart the outfits in my own Fortnite locker and putting them back together in three.js and Godot. Just for fun, and a way to try both. Jiggle physics included.

The three.js outfit viewer showing a character on a glowing display stand, with the outfit list on the left and a card of layers and secondary-motion sliders on the right — The viewer: pick an outfit, then switch layers and motion on or off.

A character mid-way through a dance emote in the viewer, with the animation list filtered to emotes and a playback bar along the bottom — Animations: any clip can be played on any body, with a scrub bar and speed.

A second outfit in the viewer, with its styles, layers and the chest, butt and thigh motion sliders in the card on the right — Chest, butt and thigh sliders set how much the jiggle chains move.

The Face tab listing hand-made expressions such as smile, laugh and wink, beside a character in the viewer — Hand-made facial expressions, with blinking.

Why

I wanted a real, messy, rigged data set to try 3D on, rather than a tutorial cube. Characters with bodies, heads, accessories, hundreds of animations and cloth and hair turned out to be a good way to learn three.js in the browser and Godot as an engine.

What it does

Viewer (three.js): pick a body, a head and accessories, or a whole outfit, assembled on one skeleton. Play any of thousands of animations, with a turntable, a rest pose and hand-made facial expressions. It works on a phone too.
Jiggle physics: spring chains for chest, hair, cloth and tails, with sliders and body collision. Dragging the character spins it, and everything keeps swinging for a moment after you let go.
Locker: reads which outfits I own by screenshotting the in-game locker, so the viewer can filter to them.
Godot side: Blender scripts turn an outfit into a rigged, animated model that Godot imports directly. Two test projects use it: a stylised smooth-voxel open world, and a 2.5D fighting game.

Under the hood

A .NET exporter reads the game's own files from my install through the CUE4Parse library, and a script rebuilds an index of everything it finds.
A small Node server feeds the viewer. Materials, textures and styles are resolved from the exports, and my choices per outfit are saved.
The Godot pipeline runs Blender headless to bake textures, merge the skeleton and retarget animations. The voxel world uses the Voxel Tools extension.
