Chris Eveleigh (whyohme) added a comment to D10936: Adjust integration weights for random walk BSSRDF Path kernel..

FYI, this behaviour is not seen in cycles-x. I've not finished reading the code so I'm not yet certain how it's been fixed.

Chris Eveleigh (whyohme) added a comment to rB9676a1f61ebe: Fix render crash in some .blend files after Persistent Data changes.

ah, ignore this - I see it's covered by T87295.

@Brecht Van Lommel (brecht) do you have an example file that crashes without this change?

For me this change causes BlenderSync::sync_recalc to think that nothing has changed (since the updates have been cleared) - so animated objects don't move when rendered. (Sorry, I've not found a solution yet).

Chris Eveleigh (whyohme) added a comment to T85703: objects rendered black on repeated CUDA renders with 'persistent images'.

thanks so much for checking this and taking the time to reproduce as well! (sorry - I had been meaning to check newer builds myself). Can confirm rB258b15da74ad has the fix.

Chris Eveleigh (whyohme) added a comment to T85703: objects rendered black on repeated CUDA renders with 'persistent images'.

in a more complex scene, comparing cycles debug output between a first and second render, these three lines are missing for the failed render:

Chris Eveleigh (whyohme) added a comment to T85671: OCIO crash/abort using Filmic Medium Contrast.

this only happens with the "Medium Contrast" look - in datafiles/colormangement/config.ocio you can see that's the only Look with no FileTransform children. Perhaps that's no longer allowed in OCIO v2?
