# Multi-Image to 3D

Create a 3D model from two to four orthographic views for better shape accuracy than single-image generation.

{% hint style="info" %}
🔒 Multi-Image to 3D is a **Pro feature.**
{% endhint %}

### 🧠 What is Multi-Image to 3D?

Multi-Image to 3D (Multi-View) generates a 3D model from **two to four orthographic views** of the same object:

* Front
* Left
* Back
* Right

The Front view is required and is used as the primary reference. The others are optional, and each one you add reduces guessing in the side and back areas.

***

### 🚀 How It Works

{% stepper %}
{% step %}

#### Prepare views

* Prepare 2 to 4 views of the same object. Front is required, then add Left, Back or Right as available.
  {% endstep %}

{% step %}

#### Upload images

* Upload each image into the matching slot (Drag & Drop or **Upload**).
  {% endstep %}

{% step %}

#### Set polycount and texture

* **Polycount** sets the triangle budget with a slider.
* **Texture** is a toggle. Leave it on to generate textures, or turn it off for geometry only.
  {% endstep %}

{% step %}

#### Generate

* Click **Generate**.
  {% endstep %}

{% step %}

#### Review & export

* Review the result in the viewer (textured/solid/wireframe) and export when ready.

{% hint style="warning" %}
Textures are embedded in .glb, .fbx, .usdz, .blend and the OBJ-ZIP option. Plain .obj, .usd, .stl, .ply and .3mf carry geometry only.
{% endhint %}
{% endstep %}
{% endstepper %}

### ✅ Best use cases

* Props and products where side/back shape matters (tools, furniture, devices)
* Reference-based modeling from orthographic sheets
* Objects with unclear depth in a single image

***

### 🔍Tips for best results

#### Keep views consistent (most important)

* Use true **orthographic** renders if possible.
* If using photos, keep the same:
  * camera distance
  * focal length
  * framing
  * object position and scale

{% hint style="info" %}
Consistent views are the single biggest factor for success.
{% endhint %}

#### Use simple backgrounds and lighting

* Plain background (no clutter)
* Even lighting with minimal shadows
* Avoid strong reflections and highlights

#### Keep the object unchanged

* One object only
* No pose/state changes between views (open vs closed, rotated parts, etc.)
* Don’t crop the object

***

### ⚠️ Limitations to Know

* Mismatched angles between views (can cause twisting/bulging/missing parts)
* Reflective or transparent materials (glass, chrome)
* Very thin details (wires, chains)
* Facial features and characters may look rough or “off”
* Generated geometry is fixed. You can retexture a model, but you cannot reshape it
* Complex geometry may need cleanup if used in games.

### 📦 Export formats

Supported export formats:

* `.glb`, `.fbx`, `.obj`, `OBJ-ZIP`, `.usd`, `.usdz`, `.blend`, `.3mf`, `.stl`, `.ply`

Recommended formats:

* ✅ **GLB** (best default)
* 🧩 **OBJ** (broad compatibility)
* 🖨️ **STL** (3D printing)

Textures are embedded in `.glb`, `.fbx`, `.usdz`, `.blend` and `OBJ-ZIP`. Plain `.obj`, `.usd`, `.stl`, `.ply` and `.3mf` carry geometry only.

### 🔁 Related tools

Use Multi-Image to 3D alongside other Sloyd tools:

* **Text to 3D**: best for fast ideation without references
* **Image to 3D**: best when you only have one image
* **Text to Image:** best for fast concepting and reference generation

***

### 🌍 Who’s It For?

Multi-Image to 3D is best for anyone who needs the shape to be closer to the real object than a single image can provide:

* **Game devs**: better silhouettes and fewer “made-up” side/back details for props
* **3D artists**: a faster starting point when you already have reference views
* **Concept artists**: turn orthographic sheets into a usable 3D blockout
* **Students/Educators**: Create 3D without touching complex software

### 🧪 Status

{% hint style="warning" %}
Multi-Image to 3D is under active development. Quality will continue to improve over time, and feedback helps guide what to prioritize next.
