OBJ retains all face connectivity.
If you are a developer, building a custom pipeline using (for volume rendering) + trimesh (for OBJ export) gives you surgical control over the vvd to obj top outcome. vvd to obj top
Unlike the OBJ format, which lists positions, normals, and UVs in separate arrays, a VVD file interleaves this data into a single structure for each vertex. A standard Source engine vertex typically includes: OBJ retains all face connectivity
| Problem | Cause | Fix | |---------|-------|-----| | Missing faces | Wrong LOD | Use LOD 0 (highest detail) | | Flipped normals | VVD winding order | In Blender: Mesh → Normals → Recalculate Outside | | UVs lost | Export settings | Ensure OBJ export includes vt lines | | Merged vertices | Importer welding | Use Noesis or disable welding in Blender import | A standard Source engine vertex typically includes: |
