World Labs Studio

Studio is where you compose, animate, and enhance your generated worlds. Connect multiple worlds, create camera paths, and export final videos.

Accessing Studio

1. Go to https://marble.worldlabs.ai
2. Open a generated world
3. Click Continue Creating (paintbrush icon) to access Studio tools
4. Or access from your worlds tab

Documentation: https://docs.worldlabs.ai/marble/create/studio-tools/

Three Core Features

Feature	Purpose
Compose	Connect and arrange multiple worlds
Record	Create camera animations with keyframes
Expand	Extend worlds beyond original boundaries

Compose Mode

Overview

Compose allows you to:

• Connect multiple generated worlds into larger environments
• Position, rotate, and scale worlds
• Remove splat artifacts at boundaries
• Create seamless transitions

Adding and Positioning Worlds

1. Add Scene: Click to browse your worlds
2. Choose World: Select from saved worlds or community
3. Position: World appears with positioning handles
4. Repeat: Add more worlds to build larger environment

Controls Panel

Property	Description
Position	Adjust X, Y, Z coordinates
Rotation	Orient worlds to align correctly
Scale	Resize worlds proportionally
Move Speed	Navigation speed (default: 3)
FOV	Field of view (default: 92)
Grid	Toggle grid visibility for alignment
Bounding	Show world boundary corners

Splat Removal

Clean Gaussian splat artifacts at world edges:

1. Select Splat Eraser tool
2. Choose brush shape (circle/square)
3. Adjust brush size
4. Paint over artifacts
5. Preview result in real-time

Splat Count: Monitor usage against your account limit (e.g., 500,000 / 2,000,000)

Fine-Tuning Connections

1. Check overlapping areas where worlds meet
2. Align ground levels—ensure floor heights match
3. Match lighting for natural blending
4. Test transitions by navigating between worlds
5. Use consistent background color across scenes

Record Mode

Overview

Create cinematic camera animations:

• Define camera path with keyframes
• Control timing and easing
• Add AI enhancement pass
• Export high-quality video

Keyframe System

Key	Action
F	Add keyframe at current position
U	Update current keyframe
Delete	Remove selected keyframe
Space	Play/pause animation

Creating Camera Paths

Step 1: Position camera

Navigate to starting view using:
- WASD: Move
- Mouse: Look
- Q/E: Up/Down
- Shift: Sprint

Step 2: Add keyframe

Press F to create keyframe at current position

Step 3: Move to next position

Navigate to next camera position

Step 4: Repeat

Continue adding keyframes along desired path

Keyframe Properties

Property	Description
Position	Camera XYZ location
Rotation	Camera orientation (pitch, yaw, roll)
FOV	Field of view
Duration	Time to reach this keyframe
Easing	Interpolation curve (linear, ease-in/out, etc.)

Easing Options

Easing	Effect
Linear	Constant speed
Ease-In	Slow start, fast end
Ease-Out	Fast start, slow end
Ease-In-Out	Slow start and end
Bezier	Custom curve control

Enhance Feature

After recording, apply AI enhancement:

1. Temporal consistency: Smooth flickering artifacts
2. Detail enhancement: Sharpen and improve quality
3. Color grading: Apply cinematic color profiles

Expand Mode

Overview

Extend world boundaries beyond the original generation:

1. Navigate to world edge
2. Look for areas where world meets unexplored space
3. Position yourself at good viewpoint
4. Click Expand button
5. AI generates new content matching existing style

Accessing Expand

• Click Continue Creating (paintbrush icon) on any generated world
• Available in the viewer or from your worlds tab

Expand Controls

Control	Action
Click edge	Select expansion direction
Drag boundary	Define expansion area
Generate	Create new world section

Expansion Scenarios

Indoor Extensions:

• Expand bedrooms into en-suite bathrooms
• Extend kitchens into dining areas
• Add hallways connecting rooms
• Create balconies from indoor spaces

Outdoor Growth:

• Expand gardens into larger landscapes
• Extend courtyards into street views
• Add pathways to new zones

Best Practices

✅ Expand in directions with good context
✅ Generate small sections, check quality
✅ Consider flow and logical navigation
✅ Think about how areas connect spatially

❌ Don't expand into empty void areas
❌ Avoid expanding where geometry is ambiguous
❌ Note: Vertical expansion (up/down) not currently supported

Limitations

• Cannot expand upward or downward (horizontal only)
• "Not within recommended area" warning indicates expansion limit
• Trajectories don't persist across page navigation
• Multiple expansions require Studio Compose to stitch together
