MetaHumans are powerful. They look real. They move naturally. But when it comes to clothing, things can get tricky. What if you already have a skeletal mesh outfit and want to use it as a cloth asset? Good news. It’s totally possible. And it’s not as scary as it sounds.
TLDR: You can turn a skeletal mesh into a cloth asset for MetaHuman by binding it correctly to the MetaHuman skeleton and enabling cloth simulation inside Unreal Engine. The key steps include weight painting, assigning the right skeleton, and using the Cloth Paint tool. Chaos Cloth does the heavy lifting for realistic movement. With a little setup, your character’s outfit will move naturally and look amazing.
Let’s break this down step by step. Keep it simple. Keep it fun.
First, What Is a Skeletal Mesh?
A skeletal mesh is a 3D model that has bones.
Those bones allow it to:
- Move
- Bend
- Animate
- Follow a skeleton
MetaHumans use very advanced skeletons. That means any clothing you use must match that skeleton properly.
If it doesn’t? Things stretch. Twist. Explode. Not ideal.
Why Use Skeletal Meshes as Cloth?
Great question.
There are two main types of character clothing in Unreal:
- Static Mesh Clothing – Simple. No bones. Limited movement.
- Skeletal Mesh Clothing – Moves with bones. Works with animation. Supports cloth physics.
If you want realistic jackets, dresses, coats, or loose fabric, skeletal mesh is the way to go.
Especially with Chaos Cloth.
Step 1: Prepare Your Skeletal Mesh
Before Unreal Engine even opens, your mesh must be ready.
In Blender, Maya, or Marvelous Designer:
- Make sure the clothing fits the MetaHuman body.
- Delete hidden body geometry underneath if needed.
- Match the MetaHuman skeleton.
- Freeze transforms.
- Apply proper scale.
Important: Your clothing mesh must be skinned to the exact MetaHuman skeleton.
If you export clothing separately, bind it to:
- metahuman_base_skel
No guessing. No shortcuts.
Step 2: Import the Clothing into Unreal
Now open Unreal Engine.
Import your FBX file:
- Select Import
- Choose your FBX
- Set Skeletal Mesh to enabled
- Choose the MetaHuman skeleton
Make sure you:
- Do NOT create a new skeleton
- Assign it to the existing MetaHuman skeleton
This step is critical.
If you use the wrong skeleton, animations will not sync.
Step 3: Attach Clothing to the MetaHuman
Now you need to connect the clothing mesh to your MetaHuman Blueprint.
Open your MetaHuman Blueprint.
Add a new Skeletal Mesh Component.
Then:
- Set the skeletal mesh to your clothing asset.
- Attach it to the body component.
- Set “Leader Pose Component” to the main body mesh.
This ensures:
- Animations transfer properly.
- The clothing follows the body.
- No lag between meshes.
Now press Play.
Your character should wear the outfit.
It moves. But it’s still stiff.
Let’s fix that.
Step 4: Convert the Skeletal Mesh to Cloth
This is where the magic happens.
Open the clothing skeletal mesh.
Go to:
Clothing Mode
If you don’t see it, enable it in Plugins:
- Chaos Cloth
- Chaos Cloth Editor
Now:
- Select the mesh section.
- Right-click.
- Choose Create Clothing Asset from Section.
Select:
- Chaos Cloth
Click Create.
Now you have a cloth asset applied to your skeletal mesh.

This step makes fabric behave like fabric.
You need to define:
- What stays stiff
- What moves freely
Select the Cloth Paint Tool.
You will paint values onto the mesh.
Think of it like this:
- 0 (Blue) = Fully locked.
- 100 (Red) = Fully simulated.
Example:
- Shoulders = Low simulation.
- Chest area = Medium.
- Bottom of coat = High.
Take your time here.
Good painting equals good results.
Step 6: Adjust Chaos Cloth Settings
Chaos Cloth has many settings. Don’t panic.
Focus on the basics first:
- Gravity Scale
- Stiffness
- Damping
- Wind Influence
If cloth is too stretchy:
- Increase stiffness.
If cloth is too jittery:
- Increase damping.
If cloth falls too fast:
- Lower gravity scale.
Test constantly.
Small changes matter.
Step 7: Add Physics Asset Collisions
Without collision, cloth goes through the body.
That looks bad.
To fix this:
- Open the MetaHuman Physics Asset.
- Add collision capsules if needed.
- Make sure thighs, torso, and arms have proper physics bodies.
Cloth interacts with these bodies.
No collision = clipping.
Good collision = realism.
Common Problems (And Easy Fixes)
Problem 1: Cloth Explodes
- Check scale.
- Apply transforms before export.
- Reset simulation.
Problem 2: Cloth Ignores Animation
- Make sure Leader Pose is set.
- Confirm correct skeleton assignment.
Problem 3: Heavy Performance Drop
- Reduce cloth vertex count.
- Simulate only necessary areas.
- Lower solver frequency.

Performance Tips
Cloth simulation is expensive.
Especially with multiple MetaHumans.
Here’s how to keep things smooth:
- Use LODs.
- Disable cloth at far distances.
- Simulate only outer garments.
- Avoid 10-layer outfits.
Games need balance.
Film projects can push higher quality.
Skeletal Mesh Cloth vs Static Mesh Cloth
| Feature | Skeletal Mesh Cloth | Static Mesh Cloth |
|---|---|---|
| Follows Animation | Yes | No |
| Supports Chaos Simulation | Yes | Limited |
| Best for MetaHumans | Yes | Not ideal |
| Performance Cost | Higher | Lower |
| Realism Level | High | Low to Medium |
If you care about realism, go skeletal.
If you care about mobile performance, simplify.
Pro Workflow Tip
Want even better results?
Create clothing in Marvelous Designer.
Then:
- Export with proper topology.
- Retopo if needed.
- Bind to MetaHuman skeleton in Maya or Blender.
- Import and simulate in Unreal.
This gives you:
- Natural folds
- Clean UVs
- Production quality cloth
Final Thoughts
Using skeletal meshes as cloth assets in MetaHumans sounds complex.
But it’s just a process.
Prepare the mesh.
Bind it correctly.
Create cloth asset.
Paint weights.
Tweak physics.
That’s it.
The more you practice, the faster it gets.
And once you see that coat flowing naturally in the wind?
Totally worth it.
MetaHumans are already realistic.
Good cloth simulation makes them unforgettable.
