# Block model animation to detailed 3D model

> Animate a block model, turn the animation into a detailed building, and build a 3D model from its frames

Animate the massing first, then let a 3D-to-video model render the animation as a real building. Frames from that video are consistent views you can feed to a multi-view 3D model.

## How it works

1. **Animate: orbit the block model 180 degrees (H3 Max)** turns the block model view into an orbit video.
2. **Block animation to detailed building animation (H3 Max 3D-to-video)** renders the orbit as the building in the design reference.
3. **Front**, **Side** and **Back view** extract the first, middle and last frames.
4. **Multi-view image to 3D (Hunyuan3D v3)** builds a 3D model from all three views.

## Tips

* Multi-view 3D models produce cleaner backs and sides than single-image ones.

## Use your own model

The image input holds a capture from our demo Rhino model, so the workflow runs as it is. To use your own model, open Rhino with the [Runchat plugin](https://docs.runchat.com/plugins/rhino.md) signed in, set up your view, and run the node marked **(optional) Rhino**. Then drag its screenshot into the image input. The scripts use only the standard display modes and match layers or materials by the keywords in their inputs, so they work on any model.
