Good morning all! I’m experiencing an issue where a render will not finish. Here’s the summary:
- I am rendering with rad with an ambient cache, using -N 12
- all tiles finish rendering except for one tile
- if I use kill -CONT pid, I see the rays increasing, but the percentage complete stuck at say 7% and does not change even given another 12 hours
- that pid is using 100% CPU as expected
I have tried killing the rad process, leaving the unf file and amb file, and rerunning rad. This goes back up to 7% faster but does not complete.
(Note a potential bug, I notice if I start a render with -N 12 it uses 12 cores, but if I kill it and rerun it it will only use 1 core. Why is this?)
I have tried killing the rad process and deleting the unf file. It’ll re-render all tiles but again get stuck on that tile.
I have tried rendering that specific tile in rvu with frame. The tile renders successfully without issue.
I have not tried rerunning rad for that final file but changing rendering settings to something lower quality.
How can I debug this?
