📝 Walkthrough

Walkthrough

Adds ObjZipResult and async def download_and_extract_obj_zip(url: str) to fetch ZIP or raw OBJ payloads, extract the OBJ and map texture images (including metallic, normal, roughness) into an ObjZipResult, and return raw OBJ data when payload is not a ZIP. Imports zipfile, BytesIO, torch and utilities like bytesio_to_image_tensor/download_url_to_bytesio. Node schemas updated to expose texture_image on TencentTextToModelNode and TencentImageToModelNode; Tencent3DTextureEditNode now exposes texture_image, optional_metallic, optional_normal, optional_roughness and is added to the extension node list. Execution paths now use the new helper and pass extracted maps through (or default them) in GLB/OBJ outputs.

- Line 59: The iterable in the extension check using a set literal in the
condition (elif any(lower.endswith(ext) for ext in {".png", ".jpg", ".jpeg",
".bmp", ".tiff", ".webp"})) is causing a lint error; change the set literal to a
sequence type (e.g., a tuple or list) so the generator iterates over a stable
sequence — update that line to use (" .png", ".jpg", ".jpeg", ".bmp", ".tiff",
".webp") or similar (referencing the same variable 'lower' and the
any(...endswith(ext)...) check) to fix pylint C0208.

- Around line 54-60: The ZIP extraction loop using zipfile.ZipFile can crash or
exhaust memory: before calling zf.read(name) for either the .obj (obj_bytes) or
textures (BytesIO(...)), check the entry size via zf.getinfo(name).file_size and
enforce an explicit max size (reject or skip entries exceeding the limit); when
decoding textures call bytesio_to_image_tensor inside a try/except and on
failure log/skip the texture and leave texture_tensor as None (so the optional
texture output can fail gracefully) — adjust code around zipfile.ZipFile, the
loop over zf.namelist(), and the variables obj_bytes, texture_tensor, BytesIO,
and bytesio_to_image_tensor accordingly.
