If you use Blender with the Faceit add-on, you may have faced a common issue: the Faceit Blender eyes not working as expected. This can be frustrating, especially if you’re trying to rig, animate, or export a character for games or movies. Let’s break down why this happens, practical ways to fix it, and what to watch out for—so you can get back to creating without headaches.
Understanding The Faceit Eye Problem
Faceit is a popular Blender add-on that makes facial rigging faster and more artist-friendly. However, many users report that the eyes don’t move, deform strangely, or disappear after applying Faceit. This is not just a minor glitch; it can break your entire rig.
Common signs include:
- Eyes are stuck and won’t follow controls.
- Eye mesh disappears or detaches from the head.
- Eye rotation is inverted or moves in the wrong direction.
Usually, these problems appear after auto-rigging or exporting to engines like Unreal Engine or Unity.
What Causes Eyes Not To Work In Faceit?
Several things can make the eyes stop working in Faceit for Blender. Here are the main reasons:
- Incorrect Eye Bone Naming: Faceit expects certain names for eye bones (like “eye.L” and “eye.R”).
- Parenting Issues: If the eye mesh isn’t parented to the right bone, it won’t follow movements.
- Weight Painting Errors: If weights are missing or wrong, the eyes won’t deform with the rig.
- Modifiers Not Applied: Unapplied modifiers (like Mirror or Subdivision) can break deformations.
- Shape Key Conflicts: Shape keys for blinking or squinting may not link to the correct bones.
- Export Settings: Wrong settings for FBX or GLTF export can cause the eyes to detach or freeze.

Step-by-step Solutions
Let’s fix the Faceit Blender eyes not working problem by tackling the most common causes.
1. Check Eye Bone Names
Faceit relies on standard bone names. Make sure your eye bones are called eye.L (left) and eye.R (right).
- In the Armature panel, find the eye bones.
- Rename them if needed. Example: Eye.L for left, eye.R for right.
- Save your file before running Faceit again.
2. Confirm Eye Parenting
The eye objects (meshes) must be parented to the correct bones:
- Select the eye mesh in Object mode.
- Hold Shift and select the armature.
- Press Ctrl + P and choose “With Empty Groups.”
- In Weight Paint mode, assign 100% weight to the eye.L or eye.R group for each eye.
This ensures each eye follows its bone perfectly.
3. Fix Weight Painting
If weights are off, eyes won’t move with the rig.
- Select the eye mesh, switch to Weight Paint.
- Use the “Add” brush and paint the eye.L (or eye.R) group with full strength.
- Check if the eyes now follow the rig.
4. Apply All Modifiers
Unapplied modifiers can break the mesh.
- Select the eye mesh.
- In the Modifiers tab, apply all active modifiers (especially Mirror and Subdivision).
- Rerun Faceit if needed.
5. Check Shape Key Links
If you use shape keys for eyes (like blinking), make sure they connect to the right controls in Faceit.
- Go to Shape Key panel.
- Make sure “Blink Left” and “Blink Right” are linked to the correct drivers.
- Adjust drivers if the eyes move in the wrong direction.
6. Export Settings
If you export to another program, use these recommended settings:
| Setting | Recommended Value | Why It Matters |
|---|---|---|
| Apply Modifiers | Yes | Keeps mesh deformations |
| Add Leaf Bones | No | Prevents extra bones in Unity/Unreal |
| Only Deform Bones | Yes | Exports only bones that move mesh |
Common Mistakes And How To Avoid Them
Even experienced users make simple mistakes. Watch for these:
- Not applying all transforms: Always use Ctrl + A to apply Rotation, Location, and Scale before rigging.
- Duplicated vertex groups: Sometimes eyes have more than one vertex group for the same bone.
- Wrong mesh origin: The eye mesh origin must match the rotation center of the eye bone.

Comparing Faceit With Other Rigging Tools
To see how Faceit stacks up, here’s how it compares with two other popular Blender facial rigging tools: Rigify and Auto-Rig Pro.
| Feature | Faceit | Rigify | Auto-Rig Pro |
|---|---|---|---|
| Facial Rig Speed | Fast | Medium | Fast |
| Eye Control Quality | Good (if setup right) | Average | Excellent |
| Beginner-Friendly | Medium | Easy | Medium |
| Game Engine Export | Yes | Limited | Yes |
Insight: Many beginners think Faceit is always easier, but Rigify’s facial controls are simpler for first-timers. However, Faceit offers more flexibility if you know how to fix setup issues.
Useful Tips For Reliable Eye Rigging
- Always backup your file before running Faceit or making big changes.
- Test eye movement in Pose mode after every major step.
- Use clear names for bones and meshes. Avoid spaces or special characters.
- Check bone rolls in Edit mode. If bone roll is wrong, eyes can twist unexpectedly.
- Read the Faceit documentation—it’s updated often and covers many specific Blender versions.
Real-world Example
Maria, a 3D artist, had the “eyes not working” problem after importing a Faceit rig to Unreal Engine. She fixed it by:
- Renaming her bones to eye.L/eye.R
- Applying all transforms and modifiers
- Correcting vertex group weights
This restored full eye control in both Blender and Unreal Engine.

Frequently Asked Questions
Why Are My Faceit Eye Controls Not Moving The Eyes?
Usually, the eye mesh is not correctly weighted or parented to the eye bones. Double-check vertex groups and parenting.
How Do I Fix Inverted Eye Movement In Faceit?
This happens if the bone roll or mesh origin is wrong. Adjust the bone roll in Edit mode and set the mesh origin to the center of the eyeball.
Are Faceit Rigs Compatible With All Game Engines?
Faceit rigs work with major engines like Unity and Unreal, but check export settings and bone names to avoid eye issues.
Can I Use Custom Eye Shapes With Faceit?
Yes, but you must set up shape keys and drivers carefully. Test movement after each step.
Where Can I Find More Help For Faceit And Blender?
Visit official forums and documentation, or check out community tutorials on YouTube. The Blender Artists Forum is also helpful.
Solving Faceit Blender eye issues takes some practice, but with careful setup and attention to detail, you’ll have your character’s eyes moving smoothly in no time.
