Random missing - textures / hdri / image aov - renger queue

[unnamed7]

I have a small setup where i render multiple jobs added to c4d Render Queue and i have some 'reliability (?)' issues.
Lets say i have 100 files, every file is same file but with one difference in material.
All works fine until, randomly, some material texture, hdri or aov image is missing. It's enough to restart that failed render and it's working fine next time...
It's totally random
Oh, and it's images saved with "Render AOV group -> Render pass file"

I'am creating all those jobs with python script - script just switches material, saves to path, adds to render queue - nothing else.

What can be wrong ? What to debug to fix this?
Unfortunatly got thousands of those renders so i cant fix it by hand

Have you tried to save scenes as different filenames to render?

python script saves modified scene as a different file with different name, then adds it to render queue.
every output file is also saved with different name, so yes, always different name
it's something with AOV system i think, those error are so random - even got some instances where mask is not working, or some luminance node.
where can i check octane logs to see if there were some errors ?

I can't tell much without seeing the problem. You can check Console window for Octane logs. Even select log output flags for better log info.

hmm i dont even understand whats happening, its like random "things" not working - like is not refreshing between files in queue, something stays in memory ?
this time looks like mask is not working ? example error image:

and 3 renders before are fine, just black parts are yellow gold, and stone material switched.

it's enough to stop render queue, checkbox check that broken render again, voila - it's fixed
can i somehow force 'reload/refresh' octane on every render ?

i'am at the point of writing script to restart whole c4d and see if thats working, but it's so much work :<

Can't be sure without seeing the script and scene. But there can be a lack on update of materials.

Could you share it with me?
