Caligari TrueSpace COB File Format
The COB file format was developed by Caligari Corporation for its 3D modeling and animation software, TrueSpace. COB files store complete 3D scene data including geometry, materials, textures, lights, and animation. Though TrueSpace is now discontinued, COB remains an essential format for preserving and converting legacy 3D content.
Key Features of COB Files
- Full 3D Scene Storage: COB files encapsulate entire scenes with objects, lighting, cameras, and animation data.
- Two Format Variants:
- ASCII COB: Human-readable format ideal for manual inspection and debugging.
- Binary COB: Compact format optimized for performance and faster loading times.
- Material & Texture Support: Includes surface colors, image textures, and basic shading information.
- Geometry Types: Supports both NURBS-based and polygon mesh 3D models for greater flexibility.
COB File Conversion Tools
Use Autoconverter and Automesher Application to import and convert COB files into modern 3D formats such as FBX, OBJ, SKP, STEP, and SAT. Our converters retain crucial data including UV mapping, materials, and mesh topology by utilizing the Open Asset Import Library (Assimp) for accurate and reliable file processing.
Note: COB files can only be imported - exporting to COB format is not supported.
USD & USDZ File Format - Universal Scene Description by Pixar
Universal Scene Description (USD), developed by Pixar, is a powerful framework for creating, editing, and exchanging complex 3D scenes. Now widely adopted in the VFX, animation, and AR industries, the USD ecosystem supports large-scale pipelines through its modular, scalable, and cross-platform architecture. USDZ is its optimized variant for mobile AR applications, especially on Apple devices.
Key Features of USD and USDZ
- Modular and Composable Architecture: USD enables efficient scene composition by referencing multiple files, allowing teams to collaborate on complex projects without data duplication or conflicts.
- Cross-Platform Interoperability: USD ensures accurate data exchange across software platforms like Maya, Blender, Unreal Engine, and more - ideal for collaborative, multi-tool workflows.
- Hierarchical and Layered Scene Representation: Easily organize 3D data using namespaces, variants, layers, and references, providing unparalleled control over versioning and detail management.
Convert USD, USDA, USDC, and USDZ Files
Our Autoconverter and Automesher Application software supports full-featured conversion for USD, USDA, USDC, and USDZ formats. Powered by the OpenUSD framework, our tools allow you to import, export, and convert USD files to popular 3D formats like GLTF, FBX, STL, OBJ, SKP, and STEP.
