# How it Works

> Understanding how Fill 3D works.

Fill 3D is designed to generate highly realistic results by emulating the professional virtual staging workflow.
Here's what Fill 3D does behind the scenes:

<Tip>
  Other AI virtual staging platforms generate disconcerting artifacts like warped geometry, altered
  colors, and more. Fill 3D is specifically designed to avoid these artifacts.

## Creating a 3D Scene

Starting with an image of an empty room like below:

<Frame caption="Input images should always be empty and well-lit.">
  <img className="rounded-xl overflow-hidden" src="https://mintcdn.com/fill3d/5C38K-Aqkd3fyCeO/images/room.jpg?fit=max&auto=format&n=5C38K-Aqkd3fyCeO&q=85&s=9d2f1e0e3c27d75c962fd91e4d950e22" alt="Sample room" width="5472" height="3648" data-path="images/room.jpg" />
</Frame>

Our debut 3D AI model `blend-1` generates a high-fidelity 3D scene with accurate room
geometry, textures, lighting, and more. The generated 3D scene is exported to [Blender](https://blender.org):

  Download the Blender scene and check it out yourself.

<Tip>
  The `blend-1` model typically takes 30-50 seconds to generate a 3D scene from an image.

## Staging the Scene

Our staging model `stager-1-preview` uses a text prompt to decide what furniture objects to place in the scene, and
how to place them. It then generates a final image using Blender's photorealistic renderer:

<img className="rounded-xl overflow-hidden" src="https://mintcdn.com/fill3d/5C38K-Aqkd3fyCeO/images/staged3.jpg?fit=max&auto=format&n=5C38K-Aqkd3fyCeO&q=85&s=828cdc96f1757e380ad080fe1acafa46" alt="Placing furniture" width="1600" height="1066" data-path="images/staged3.jpg" />

<Warning>
  Our `stager-1-preview` virtual staging model is still in preview, and currently only stages
  with bedroom furniture. [Learn more](/workflows/staging).
