### Critical Missing Features

**🔴 Critical Priority** (Required for normal mapping):
1. `Mesh.vertex_tangent` - Tangent vectors for TBN matrix
2. `Mesh.vertex_bitangent` - Bitangent vectors for TBN matrix
3. `Mesh.vertex_color` - Vertex color data
4. `Texture.content` - Embedded texture data
**🔴 Critical Priority** (COMPLETED ✅):
1. ~~`Mesh.vertex_tangent`~~ - ✅ Implemented
2. ~~`Mesh.vertex_bitangent`~~ - ✅ Implemented
3. ~~`Mesh.vertex_color`~~ - ✅ Implemented
4. ~~`Texture.content`~~ - ✅ Implemented

**🔴 High Priority** (Strongly recommended):
5. `Node.node_to_world` - World transform matrix
6. `Texture.has_file` - Texture type detection
7. `Texture.uv_set` - Multiple UV channels
**🔴 High Priority** (COMPLETED ✅):
5. ~~`Node.node_to_world`~~ - ✅ Implemented
6. ~~`Texture.has_file`~~ - ✅ Implemented
7. ~~`Texture.uv_set`~~ - ✅ Implemented
8. ~~`Texture.wrap_u`, `Texture.wrap_v`~~ - ✅ Implemented
9. ~~`Node.geometry_transform`~~ - ✅ Implemented
10. ~~`Node.node_to_parent`~~ - ✅ Implemented

**🟡 Medium Priority**:
8. Scene special collections (videos, shaders)
9. Mesh multi-material support
10. Node geometry transform
11. Scene special collections (videos, shaders)
12. Mesh multi-material support (`face_material`)
13. Mesh faces data (non-triangulated polygon access)

**🟢 Low Priority**:
11. NURBS objects (curves, surfaces, etc.)
12. Advanced features (cache, audio, LOD, etc.)
14. NURBS objects (curves, surfaces, etc.)
15. Advanced features (cache, audio, LOD, etc.)
16. Texture layers and shader references
