🚀 Convert COB to GLTF: Caligari File to GLB Transmission Format Conversion

How to Convert COB to GLTF❓

A faster, smarter way to convert COB to GLTF. Follow our step-by-step guide and experience seamless conversion with our industry-leading tool:

  1. 📥 Download and Install

    Download and install Autoconverter on your system. This application will let you to convert your COB files to GLTF format - no additional CAD software required.

  2. 📂 Open Your COB File

    Go to File > Open… to load your COB file (*.cob, *.scn), or drag and drop it directly into the application window. The model loads into the 3D viewport for inspection before converting.

  3. 💾 Save As GLTF Format

    Go to File > Save As…, select GLTF (*.gltf, *.glb) as the output format, choose your destination folder and filename, then click Save to complete the COB to GLTF conversion.

COB 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.

GLB GLTF and GLB 3D File Format

The GLTF (GL Transmission Format) and GLB file types are modern open standards developed by the Khronos Group for efficient storage, transmission, and rendering of 3D models. Designed for the web, gaming, VR/AR, and real-time applications, these formats enable compact, high-performance 3D asset workflows across platforms.

Key Features of GLTF and GLB Files

  • GLTF Versions:
    • GLTF 1.0: Supports basic geometry, textures, simple materials, and skeletal animations with joint hierarchies.
    • GLTF 2.0: Adds advanced features like PBR (Physically Based Rendering) materials, Draco compression, morph targets, skinning, and enhanced animation capabilities.
  • ASCII vs Binary: GLTF files are human-readable (JSON format), while GLB files combine 3D data, textures, and materials into a compact, binary format for faster loading and easier distribution.
  • Embedded Textures: Both GLTF and GLB can embed textures directly, creating self-contained 3D assets ideal for web and mobile applications.

Convert GLTF and GLB Files

With Autoconverter and Automesher Application, you can easily import, export, and convert GLTF and GLB files to formats like OBJ, FBX, STL, and more. Our software supports Draco compression, enabling significantly smaller file sizes while preserving the quality and performance of your 3D assets.
