What is the best file format for collaborative 3D design projects?

The best file format for collaborative 3D design projects is USD (Universal Scene Description). - **Cross-software compatibility**: Works seamlessly with tools like Blender, Maya, and CAD, ensuring all collaborators access consistent data without format conflicts. - **Data integrity & non-destructive edits**: Preserves layers, materials, and animations, allowing real-time updates without overwriting originals—unlike static formats (e.g., OBJ, STL) better for final model sharing. - **Streamlined workflows**: Plugins for most 3D software simplify integration, reducing collaboration friction. Overall, USD balances compatibility, flexibility, and efficiency, making it ideal for team-based 3D design.
