– This happens when an object has a material that is not a Sollumz material. Convert all materials to Sollumz‑compatible ones before attempting to export.
Standard tools frequently lose the original pivot points and scale values. When you import the OBJ into blender or 3ds Max, the mesh might appear microscopically small or floating hundreds of units away from the center grid.
To achieve a flawless conversion using the OpenIV and Blender (Sollumz) ecosystem, follow this optimized workflow:
For years, the standard workflow for modders wanting to edit these assets involved exporting them to more universal formats. However, standard conversion utilities often leave a lot to be desired. Upgrading to a better YDD to OBJ converter can instantly eliminate hours of tedious cleanup and elevate the quality of your custom game assets. The Core Problem with Standard Converters ydd to obj converter better
If your .ydd file is a "Yodot Data Recovery" file, you aren't looking for a 3D converter.
CodeWalker is a powerful research tool for GTA V that has evolved into a fully-fledged editor. While primarily used to view the game world, it has robust export capabilities.
OpenIV is the foundational modding tool for RAGE engine games. While it can export resources, pairing it with dedicated 3D software scripts yields the highest fidelity models. – This happens when an object has a
CloudCompare is the gold standard for point cloud processing. It isn't a one-click web tool, but it is infinitely better.
You can write a Python script using the yaml library to read the YDD file and convert its content into OBJ format.
: Instead of exporting as a raw .obj immediately, export the file as OpenFormats (.gdrv) . This format captures the skeletal structure and texture paths that a standard .obj ignores. When you import the OBJ into blender or
| Issue | Cause | Better Converter Fix | |-------|-------|----------------------| | | YDD uses opposite winding order | In Noesis: Tools → Model Options → Reverse culling before export | | Missing UVs | YDD stores UVs in separate chunk | Use Assimp + manual --uv flag | | Textures not loading | MTL points to wrong path | Edit .mtl file: replace map_Kd textures/texture.png with map_Kd ./texture.png | | Model appears small | YDD units = millimeters | Scale factor 0.001 in export | | Only LOD0 exported | Plugin defaults to low LOD | In Noesis script: change lodIndex = 0 to lodIndex = -1 (highest) |
Use the Import > Codewalker XML option to bring in the .ydd.xml file generated by OpenIV.
Before finding a better converter, you must understand the anatomy of a YDD file. YDD is often associated with point cloud and 3D scan data, commonly generated by terrestrial laser scanners or specific GIS (Geographic Information System) software like LiDAR 360 or certain Chinese surveying instruments.
Right-click the .ydd file and select "Export to open formats (.odd)" . This creates a readable folder structure with the mesh data.
