- Create render-worker/ with Dockerfile (Ubuntu + cadquery + Blender via host mount) - Add render-worker/check_version.py: verifies Blender >= 5.0.1 at startup, Exit 1 on failure - Add render-worker/scripts/: blender_render.py, still_render.py, turntable_render.py - Create backend/app/services/render_blender.py: direct subprocess rendering - convert_step_to_stl() and export_per_part_stls() using cadquery - render_still(): STEP → STL → PNG via Blender subprocess - is_blender_available(): detects BLENDER_BIN env for render-worker context - Create backend/app/domains/rendering/tasks.py: render_still_task + render_turntable_task - Update step_processor.py: use subprocess path when BLENDER_BIN env is set (render-worker) - Update step_tasks.py: generate_stl_cache uses direct cadquery instead of HTTP - Remove blender-renderer and threejs-renderer from docker-compose.yml - Replace worker-thumbnail with render-worker (Ubuntu + cadquery + Blender mount) - Remove Docker SDK from backend Dockerfile (was only for flamenco scaling) - Update .env.example: BLENDER_VERSION=5.0.1 documented - Update celery_app.py: include domains.rendering.tasks in autodiscover Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
