Sovereign Render Worker
Fixed Python script — run this on your local machine or Google Colab to process render jobs.
Required Assets — Live From The Queue
No jobs in the queue right now — nothing to stage.
Blender Worker — Golden Schema
Save this as /SOVEREIGN_SYSTEM/blender_worker.py. It claims jobs, runs the integrity check against your ASSETS folders, renders headless, and reports back.
Directory Schema
/SOVEREIGN_SYSTEM/ ├── ASSETS/ WORLDS/ AVATARS/ CARS/ WIDGETS/ ├── QUEUE/ PENDING/ PROCESSING/ CONFLICT/ └── OUTPUT/ RAW/ FINAL/ GIFS/

ENV SOVEREIGN_ROOT — defaults to /SOVEREIGN_SYSTEM

Bugs Fixed From Original
✗ response.status_with == 200→response.status_code == 200 (typo was breaking all queue polling)
✗ No job result reporting→Added report_result() so Base44 marks jobs SUCCESS/FAULT
✗ No avatar PNG rendering→Loads avatars/{id}.png and pastes onto frame if exists
✗ Static pink box only→Full animated lip-sync head with viseme cycling + breathing bob
✗ No dialogue text on screen→Progressive text reveal synced to frame progress
✗ No continuous loop→while True loop — polls queue every 10s, processes all jobs
How To Use
1. Download the script below
2. Put your avatar PNGs in avatars/ folder (named by avatar ID)
3. Install: pip install pillow requests + FFmpeg on your system
4. Run: python sovereign_worker.py
5. Launch jobs from the MP4 Render Lab page — worker picks them up automatically
6. MP4s appear in output_cinema/ — upload them and paste URLs into the pipeline
