Use your head in Unity, Godot or three.js.

Which file for which engine

Both are life size. Hair is not in the GLB or the FBX: in Unreal, MetaHuman grooms replace it; in other engines, add hair of your own.

Can I use a MetaHuman in Unity?

A FaceNinja head is your own file, on MetaHuman topology, under our terms: use it in any engine. A MetaHuman you build in MetaHuman Creator comes under Epic's licence, which since June 2025 also allows other engines and tools (Epic's licence page).

Unity: import the FBX

1. Bring in the FBX

   Download the FBX with ARKit shapes and drop it into your project's Assets folder.

2. Check the import settings

   On the Model tab, keep Convert Units on, so the centimetres become metres, and Import BlendShapes on (the default). Apply.

3. Extract the materials

   On the Materials tab, extract the textures and materials so you can edit them. In URP or HDRP, convert the materials to the pipeline's Lit shader.

4. Find the shapes

   Place the head in a scene. The Skinned Mesh Renderer lists the 52 shapes under BlendShapes, named after the ARKit shapes.

5. Drive them from code

   Weights in Unity run from 0 to 100.

   CodeCopy

   // Unity (C#): the head's SkinnedMeshRenderer; Unity blend shape weights run 0–100
   var smr = GetComponentInChildren<SkinnedMeshRenderer>();
   var mesh = smr.sharedMesh;
   for (int i = 0; i < mesh.blendShapeCount; i++)
       if (mesh.GetBlendShapeName(i).EndsWith("jawOpen"))
           smr.SetBlendShapeWeight(i, 60f);

Prefer GLB? Unity reads it with a glTF importer package, such as glTFast.

Godot 4: import the GLB

1. Bring in the GLB

   Download the GLB with ARKit shapes and copy it into your project. Godot imports it as a scene, in metres.

2. Find the shapes

   Open the scene and select the head's MeshInstance3D. The Inspector lists the blend shapes by their ARKit names under Blend Shapes.

3. Drive them from code

   Weights in Godot run from 0 to 1.

   CodeCopy

   # Godot 4 (GDScript): the head's MeshInstance3D; weights run 0–1
   @onready var head: MeshInstance3D = $Head
   func _ready():
       var i := head.find_blend_shape_by_name("jawOpen")
       if i >= 0:
           head.set_blend_shape_value(i, 0.6)

three.js: load the GLB

1. Load it with GLTFLoader

   The head opens as several meshes (skin, eyes, teeth and so on); each one carries the same 52 shape names.

2. Set the shapes by name

   morphTargetDictionary maps each ARKit name to its index in morphTargetInfluences; weights run from 0 to 1.

   CodeCopy

   // three.js: every mesh of the head carries the same 52 names; weights run 0–1
   import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
   const gltf = await new GLTFLoader().loadAsync('head.glb');
   gltf.scene.traverse((o) => {
     const i = o.morphTargetDictionary?.jawOpen;
     if (i !== undefined) o.morphTargetInfluences[i] = 0.6;
   });
   scene.add(gltf.scene);

3. Clear eyes

   For clear, reflective eyes in three.js, download with the cornea=transmission option, or swap the cornea materials when you load the file (docs).

We loaded this sample's GLB in three.js for this guide: it opens as 6 meshes, and each one lists all 52 ARKit names.

Good to know

• Same mesh, same rig. Every head has the same vertex order and UVs, so a setup you make for one head works for all of them.
• Scale. Every file is life size. The measured download option scales a head to an estimate of the person's size.
• Lighter files. Ask for 2K textures with the texture_size download option when 4K is more than you need.
• The web preview is not for engines. Use the GLB or FBX, not the compressed preview the web app shows.

Questions about heads in Unity, Godot and three.js

01Can I use a MetaHuman in Unity?

A FaceNinja head is a plain FBX or GLB, so yes. A full MetaHuman built in MetaHuman Creator may also be used in other engines under Epic's licence since June 2025; check its terms.

02Do the 52 blendshapes come in?

Yes, by their ARKit names: as BlendShapes on the Skinned Mesh Renderer in Unity, Blend Shapes on the MeshInstance3D in Godot, and morph targets in three.js.

03Is there hair?

Not in these files. In Unreal, MetaHuman grooms supply it; in other engines, add hair of your own.

04Which format is smaller?

The GLB with ARKit shapes is about 105 MB with 4K textures, and the static GLB about 65 MB. 2K textures make both smaller.
