Multiple Failures in Update and 3D Generation (Trellis-2)

[koloved]

Environment:

App Version: Modly v0.2.1

Platform: Windows (B:\ drive installation)

Sub-modules: Trellis-2 Extension

Description
The application is currently experiencing two distinct critical failures: an HttpError: 404 during the auto-update check and a RepositoryNotFoundError (401/404) combined with a ModuleNotFoundError during 3D generation using the Trellis-2 pipeline.

Issue 1: Updater Failure (404)
The electron-updater fails to locate the latest.yml file in the GitHub release artifacts.

Target URL: https://github.com/lightningpixel/modly/releases/download/v0.2.1/latest.yml

Error: HttpError: 404

Impact: Users are unable to check for or pull the latest application updates.

Issue 2: Generation Failure (Trellis-2 Pipeline)
When attempting to run 3D generation, the process crashes due to missing dependencies and unreachable HuggingFace repositories.

A. Missing Module:

Error: ModuleNotFoundError: No module named 'o_voxel'

Traceback Location: ...\extensions\trellis-2\vendor\trellis2\models\sc_vaes\fdg_vae.py, line 20.

Note: It appears the o_voxel dependency was not built or installed during the extension setup.

B. HuggingFace Auth/Repository Error:

Error: huggingface_hub.errors.RepositoryNotFoundError: 401 Client Error

Target Repo: ckpts/shape_dec_next_dc_f16c32_fp16

Details: The application attempts to fetch .json config files from a repository that is either private, requires a token, or no longer exists at that specific path.

[Lorchie]

Hello,
Can you try the new release plz ?
https://github.com/lightningpixel/modly/releases/tag/v0.3.0
Thx you

[JensWinkler91]

I couldn't install the extension as well.
With v.0.3.1. I receive the error: manifest.json: required field "nodes" missing or empty.

[iammojogo-sudo]

Hopefully I can add valuable bug info. I get this;

[Lorchie]

We're working on it

[iammojogo-sudo]

We're working on it

Do you mind if I create a setup for a different model and try to load it in and play around with it? If it works, I can give you the files to add to your repo :)
