Auto-opened by architect for task 25d5046bb30c.

Dashboard: http://cloudbison:7070/task/25d5046bb30c

User Story: As a creator, I can import glTF models and textures into my experience so that I can use custom 3D assets.

Task: Extend the existing asset upload endpoint (POST /api/assets/{id}/upload) to detect glTF/GLB files and extract metadata (mesh_count, vertex_count, has_animation, texture_refs, bounding_box). Add glTF-specific fields to the Asset model and response schema.

Files:

backend/app/models/asset.py — add glTF metadata fields (mesh_count: int, vertex_count: int, has_animation: bool, texture_refs: list[str], bounding_box_min: list[float], bounding_box_max: list[float])
backend/app/routers/assets.py — add glTF detection in upload endpoint, metadata extraction using a lightweight glTF parser (e.g., gltf or trimesh), store metadata in metadata_json column
backend/app/config.py — add GLTF_MAX_FILE_SIZE_MB setting if needed

Acceptance Criteria:

POST /api/assets/{id}/upload with a .glb/.gltf file extracts mesh_count, vertex_count, has_animation, texture_refs, and bounding box
Non-glTF files upload normally without error (no regression)
Metadata is stored in metadata_json and returned in GET response
File stored on disk at configured upload directory
Unit tests for metadata extraction (mock glTF binary)

Dependencies: None (builds on existing asset infrastructure)

Dashboard: http://cloudbison:7070/task/25d5046bb30c **User Story:** As a creator, I can import glTF models and textures into my experience so that I can use custom 3D assets. **Task:** Extend the existing asset upload endpoint (`POST /api/assets/{id}/upload`) to detect glTF/GLB files and extract metadata (mesh_count, vertex_count, has_animation, texture_refs, bounding_box). Add glTF-specific fields to the Asset model and response schema. **Files:** - `backend/app/models/asset.py` — add glTF metadata fields (mesh_count: int, vertex_count: int, has_animation: bool, texture_refs: list[str], bounding_box_min: list[float], bounding_box_max: list[float]) - `backend/app/routers/assets.py` — add glTF detection in upload endpoint, metadata extraction using a lightweight glTF parser (e.g., `gltf` or `trimesh`), store metadata in `metadata_json` column - `backend/app/config.py` — add `GLTF_MAX_FILE_SIZE_MB` setting if needed **Acceptance Criteria:** - POST `/api/assets/{id}/upload` with a `.glb`/`.gltf` file extracts mesh_count, vertex_count, has_animation, texture_refs, and bounding box - Non-glTF files upload normally without error (no regression) - Metadata is stored in `metadata_json` and returned in GET response - File stored on disk at configured upload directory - Unit tests for metadata extraction (mock glTF binary) **Dependencies:** None (builds on existing asset infrastructure)
