One normal map for every pose
The folds stay put while the body moves under them. Players don't name it — they just feel the cloth is dead.
Looma · Cloth wrinkles for real-time
Simulated folds.
Simulated folds.
Real-time cost.
Looma turns cloth simulation into pose-driven wrinkle maps. Its Unreal Engine runtime reads the skeleton every frame and plays them back: folds that follow the body, at a fixed shader cost.

Wrinkle maps
As the arms rise, the folds follow: five wrinkle maps of a T-shirt pattern hand over to each other, live in your browser. An illustration of the job the Unreal runtime does every frame.

The problem
Cloth has always made you choose.
Fine folds need dense cloth
Small wrinkles want dense meshes and heavy solvers. Fine for a hero shot; the budget runs out long before a crowd does.
A map per pose, weeks per garment
And the maps never quite agree with each other, so wherever two of them blend, the folds shimmer.
Looma is the third way: folds simulated offline, pose by pose, from one consistent cloth — then played back from the skeleton for the price of a few texture samples.
Two halves, one pipeline
An atelier for the maps.
An atelier for the maps.
A runtime for the motion.
Most of the craft happens in Looma, where cloth is simulated, baked and refined into maps. The runtime carries the result into the game, where it has to hold up at sixty frames a second.
Desktop app for Windows
Where the maps are made.
A native application that takes a garment from FBX to a finished set of wrinkle maps: pose library, cloth simulation, wrap, bake, paint, sculpt and blend preview — in one window, without Maya.
- Built-in cloth simulation on CPU or GPU, pose after pose
- Raycast and surface-projection normal bakes
- Blend Space: check any mix of poses before Unreal does
- Maps land in your Unreal project by themselves

Cloth Wrinkle Solver
The runtime half of Looma: an AnimGraph node and a component that read the pose every frame and drive the cloth material. One material graph, however many poses you add.
- Folds that follow the body, frame by frame
- No empty frames, no popping between poses
- An analyzer that picks the poses from your animations
How it works
Unreal picks the poses. Looma makes the maps. Unreal plays them.
Analyse
The analyzer reads your animations and picks the poses worth a wrinkle map.
Simulate
Bring the pose set into Looma and simulate the whole set, on CPU or GPU.
Bake & refine
Wrap the simulated cloth onto your game mesh and bake. Paint, sculpt, and preview any blend.
Pack & send
Two maps per texture if you like. They arrive in your Unreal project and are imported for you.
Play
Every frame the runtime reads the skeleton and shows the folds that fit the pose.
Looma
Everything between the simulation and the texture.
Every step that used to need Maya, a simulator, a baker and a texture editor — in one native window, with one undo history and one scene file.
Pose library
Pull poses from animation takes, or author new ones by turning joints.
Cloth simulation
Built-in solvers on CPU or GPU, with pause, resume and grabbing the cloth right in the viewport.
Wrap & bake
Carry the simulated folds onto your game mesh and bake by raycast or surface projection.
Paint & sculpt
Smooth, repair seams, clone. Sculpt a pose with brushes, masks and layers — and re-bake.
Blend Space
Mix poses and see exactly the cloth the game will show, before it ever reaches Unreal.
Zones
Paint regions of the garment, mirror them, and decide per pose where the cloth hugs the body.
Export & pack
Pick the final maps, pack two into one texture, and send them straight to your Unreal project.
Assistants
Let Claude or Codex prepare, check and start bakes in your Looma window through MCP.
Cloth Wrinkle Solver · Unreal Engine 5.8
Folds that follow the body, frame by frame.
The runtime reads the driver bones every frame and shows the folds that fit the pose — the ones you simulated and approved in Looma.
- No empty frames.Wherever the pose goes, there are folds. They don't drop out between the poses you authored.
- No popping.Moving from one pose to the next is a smooth hand-over, not a switch.
- Calm on fast motion.A guard on how quickly folds may change keeps snaps and quick turns from flickering.
- One material graph.New poses are new slices of a texture array. The shader and its cost never change.

In the lab
Cloth is where we start.
The same idea — heavy simulation offline, light playback in the engine — goes well beyond wrinkles. Here's what we're building next.
Deformation to rig
Turn complex deformation into a game-ready skinned rig that runs in any engine.
Cloth from video
Film a fabric, get a Chaos Cloth asset tuned to match it — and optimised for games.
Physics over animation
A physical layer on top of your animation: characters that react to the world without losing their performance.
Do I need Maya or Python?
No. Looma is a standalone Windows application. Bring a skinned garment as FBX, the body as FBX, and your poses — Looma does the rest.
Can I use my own cloth simulator?
Yes. Looma can export per-pose collider clips for an external simulator, and it bakes from any high-resolution OBJ that sits in the same space as your game mesh.
Which Unreal versions and platforms?
The runtime targets Unreal Engine 5.8 on Win64 and is built for Chaos Cloth. Looma runs on Windows x64.
Can I keep my own cloth material?
Yes. Drop our material function into it, or have the runtime write one scalar parameter per pose and wire them however you like.
What does it cost at runtime?
A fixed handful of texture samples per pixel and a small per-character solve on the CPU. Adding poses changes neither.
Bring a garment. We'll show it moving.
We're onboarding a small group of studios for early access. Send us your cloth and a few animations, and we'll take it through the pipeline with you.
