## FAQ

### What does "Not within recommended area" mean?

This warning appears when you're either too close to existing content or beyond the limits for expansion. It helps you identify where new content can be generated.

### How do I know where I can expand?

Look for areas where your world meets unexplored or blurry spaces. These boundary zones are where expansion is possible.

### Will new areas match my existing world's style?

Yes, the expansion system analyzes your existing world's visual style, architecture,
and aesthetic to generate new areas that naturally fit and connect with your current environment.

### Can I expand in multiple directions?

Currently, you can perform one expansion of your world in different directions. You can
export the results to studio for stitching.

### What happens if I don't like an expansion?

Each expansion creates a new version while preserving previous states. You can return
to earlier versions or try expanding in different directions from your original world.

### How do expansions connect to existing areas?

The system automatically creates seamless transitions between your existing world and
new areas, ensuring proper lighting, scale, and architectural continuity at the
connection points.

### Can I expand upwards or downwards?

Not at the moment.
