YDD → OBJ Converter — How It Works

What YDD is

  • YDD is a 3D model file format used by some game engines (notably GTA modding) to store geometry, meshes, materials, and LODs.

Conversion overview

  1. Parse YDD container: Read header, section table and metadata to locate mesh and material blocks.
  2. Extract mesh data: Get vertex positions, normals, UVs, indices, and vertex colors from mesh buffers. Handle multiple submeshes/LODs.
  3. Transform coordinates: Convert coordinate system (e.g., right-handed ↔ left-handed), axis swaps, and unit scaling as needed.
  4. Apply skinning & weights (optional): If YDD stores bone indices and weights, either export them to an extended OBJ/MTL or bake deformations.
  5. Convert materials: Map YDD material references and texture paths to an OBJ-compatible MTL file; translate shader parameters to standard diffuse/specular/normal maps where possible.
  6. Write OBJ file: For each mesh/submesh, output vertices (v), normals (vn), texture coords (vt), and faces (f). Create separate objects/groups for submeshes.
  7. Write MTL file: Reference textures with correct relative paths and set material properties that approximate the original look.
  8. Handle LODs & multiple meshes: Export each LOD as separate OBJ files or include LODs as numbered objects, depending on user choice.
  9. Post-process (optional): Recalculate normals, optimize indices, weld duplicate vertices, and generate tangent space for normal maps.

Input Parsing
The converter reads the binary or text-based YDD file, interpreting its custom geometry structure—vertices, faces, normals, texture coordinates, and any hierarchy data.

  • python ydd_to_obj.py --input model.ydd --textures folder/ --output model.obj
  • Then convert DDS textures: magick convert texture.dds texture.png

Understanding what you are converting helps ensure a high-quality result: YDD → OBJ Converter — How It Works What YDD is

The standard method involves extracting the raw game data into an intermediate "open" format before final conversion to OBJ. YDD is a 3D model file format used

Converting YDD to OBJ is rarely a one-click process; it typically involves extracting the data into an intermediate "open" format before it can be exported as an OBJ. Extraction and Unlocking:
