Chisel Scene: 3D World Blocking

Use the Chisel Scene to quickly block out 3D spaces and create the foundation for detailed worlds. This tool lets you build geometric layouts that serve as the base structure for your generated environments.

​

Getting Started with Chisel Scene

Enter Chisel from the omnibox, select 3D Input mode, and enter Chisel by Start. The Chisel Scene interface provides essential tools for 3D world creation:

• 3D Viewport: The main canvas where you build your world geometry
• Geometry Panel: Access tools like Walls and Panorama Camera
• Template Options: Upload GLB or FBX models to start from existing geometry
• Generation Controls: Text prompt input and Generate button

​

How to Block Out Walls for a Room

To create a basic room structure:

1. Start with the Wall Tool: In the Geometry panel, select Walls
2. Draw Wall Boundaries: Click and drag in the 3D Viewport to define wall perimeters
3. Close the Room: Connect your final wall segment back to the starting point
4. Adjust Height: Use the wall handles to modify wall height as needed
5. Add Doorways: Create openings by selecting wall segments and adjusting them

​

How to Set Up Camera Views

Position your viewpoint for world generation:

1. Select Panorama Camera: Click on Panorama Camera in the Geometry panel
2. Position the Camera: Place it where you want the generated view to originate
3. Adjust Height: Drag the camera vertically to set the viewing height
4. Orient the View: Rotate the camera to face the desired direction

​

How to Upload Reference Geometry

Start with existing 3D models:

1. Click Upload: Select Upload a glb or fbx model in the template section
2. Choose Your File: Browse and select your 3D model file
3. Position the Model: The uploaded geometry appears in the viewport
4. Scale if Needed: Adjust the model size using the transformation handles

​

How to Generate Your World

Transform your blocked-out geometry into a detailed environment:

1. Add a Text Prompt: In the text input, describe your desired environment (e.g., “modern kitchen”)
2. Click Generate: Press the Generate button to create your world
3. Wait for Processing: The system will generate detailed geometry based on your blocks and prompt

FAQ

​

What is the Chisel Tool?

The Chisel tool lets you modify and refine existing geometry by carving, extruding, or reshaping elements.

​

What does the Extrude Tool do?

The Extrude Tool (Z key) extends selected surfaces outward or inward, allowing you to create depth and volume from flat shapes.

​

What is the Wall Tool used for?

The Wall Tool (X key) specifically creates vertical wall segments, perfect for defining room boundaries and architectural elements.

​

How do I delete geometry?

Use the Delete tool () to remove selected elements from your scene. You can also press the Delete key after selecting objects.

​

What does the Undo function do?

Undo (⌘Z) reverses your last action, letting you step back through your modeling history if you make mistakes.

​

When should I use Public Mode?

Enable Public Mode when you want your created world to be visible to other users in the community gallery. Leave it disabled for private projects.

​

What file formats can I upload?

The template uploader supports GLB and FBX file formats for 3D models. These are common formats exported from most 3D modeling software.
