Key Features

• Instant Export: Export directly to Assetto Corsa - no Blender or ksEditor needed!
• Satellite Tracing: Import real-world locations and trace roads from satellite imagery
• Terrain Generation: Automatically fetch and generate accurate 3D terrain heightmaps
• High Resolution Roads: Create physics roads with adjustable road noise and camber
• Procedural Assets: Easily place walls, kerbs, signs, trees and other trackside objects

Getting Started

When you first open TreCorsa, you'll see the editor interface with a toolbar on the left. Click "Start Creating" to begin building your track.

You can immediately start creating tracks, but to save and export your work, you'll need to sign in with Google (closed beta).

2. Draw your roads - Create your track layout using the Road tool. Adjust road width and properties as needed
3. Draw your surfaces - Use the Surface tool to add different surface types to your track
4. Add camber to roads - Use the Camber tool to add banking to corners and elevation changes
5. Add kerbs - Place kerbs along road edges using the Kerb tool
6. Add walls - Place safety barriers and walls around your track
7. Add details - Place trees, signs, and other props to bring your track to life
8. Add Physics Road - Add physics road to your track using the Noise Labs tool. More info here
