One "Queue Export" click now renders the EXR sequence, then rebuilds the shot
headlessly with the studio slate/overlay template to produce the delivery MOV
and review MP4. Implements RenderPipeline2 phases 1-2 plus the preview stage.
Server:
- New models Export, RenderJob, ExportEvent, Machine, WorkerHeartbeat, plus
Project.deliveryConfig and per-submission slate fields (Export.vfxScope,
Export.submissionNote, inherited from the shot's previous export).
Both migrations are purely additive; no existing column is touched.
- lib/render-pipeline: server-enforced state machine, transactional version
increment with supersede, atomic FOR UPDATE SKIP LOCKED claim gated by
machine availability windows, and a lease reaper run from instrumentation.ts.
- /api/ext/* endpoints for the panel and workers; session-auth mirrors under
/api/render and /api/machines for the web UI.
- Pipeline pages: render queue, export detail, machine monitoring, plus an
Exports tab on shot detail.
RenderWorker (.NET 8 Windows service, new):
- Registration, heartbeat as cancel channel, claim loop, aerender runner with
progress parsing and stall watchdog, crash recovery and disk-spooled
reporting that survives server downtime.
- Preview stage: headless AE assembles the preview comp into a throwaway AEP
with both output modules queued, then a single aerender pass renders them.
Preview jobs are not claimed while an interactive AE session is open, so an
artist's project is never taken over.
AE panel: Queue Export with live status polling, urgent flag, retry, and the
VFX Scope / Submission Note fields. Every existing panel action is unchanged.
Preview chaining ships disabled behind SystemConfig preview.enabled.
