4. The tool will automatically generate a road mesh that conforms to the terrain.

Customizing the Road

1. Use the tool's options to adjust road width, curvature, and elevation.
2. Apply road textures and materials to the road mesh using the tool's material settings.
3. Add road details like markings and barriers if the tool provides these options.

Integrating and Refining the Road

After creating the road, you may need to make additional refinements and integrate it into your game environment.

Refining the Road

Testing the Road

Finally, test the road in your game to ensure it meets your expectations:

1. Press Play in Unity to run your game.
2. Navigate the road using a test vehicle or character to check for visual or gameplay issues.
3. Make any necessary adjustments based on the test results.
