Hello everyone,
Running AYON + Blender 5.1.1 + Deadline 10.4.1 on a small farm. Render submission goes through cleanly, all Deadline tasks complete with no errors, but a subset of frames are silently missing from the Compositor File Output Node destination.
Setup:
- AYON launcher 1.5.4, blender addon 1.1.3 (also tested with 1.0.11), deadline addon 0.7.2, core 1.9.1
- Blender 5.1.1
- Output: PNG via Compositor File Output Node “Main”, slot “Beauty”
- Render path is on an SMB share (
W:\...\v037\)
Symptom:
On a 251-frame render (chunks of 2), 12 frames were missing at the final destination (Main.0952-0953Beauty.png, Main.0956-0965Beauty.png). The tmp/ folder contained all 251 PNGs from the scene render output. Deadline reported every render task as 100% complete with no errors. The publish job then failed on validate_expected_and_rendered_files with “Missing expected files” as the frames were missing in the final destination folder.
Resubmitting only the failed tasks worked. No code or scene change — same exact tasks succeed on the second attempt.
As far as I understood, blender renders its frames in the tpm folder, loads them back into the compositor and then AYON gets them from there. So the compositor saving out the frames at the final destination is the step that seems to be failing for me.
Question:
- Has anyone seen the Compositor File Output Node silently fail to write frames under farm conditions? Or what could be the cause of the compositor not writing out the frames?
I tried to find which script is responsible for that step but couldn’t find it.
Thanks!
