Have you tried clearing the baked data then trying again?

What does “kSuccess == m_Result” and "Integrate failed on Light Transport job" mean at all?

It means that one of the jobs calculating lighting failed somehow. Please file a bug report and post the case number here. Thanks!

I’m having the same problem after weeks of no issues. It just started happening today.

I figure out what the problem is for. It will happens if you are out of disk space in your windows drive.
Because of GI cache folder

I’m having this error and I have 130Gb left

I have this problem too. I have both RAM and HDD memory free so it shouldnt be an issue.

Same errors:
+999 errors all of them says

kSuccess == m_Result
Integrate failed on Light Transport job

This could also happen if the light transport job keeps crashing and restarting. We have fixed an issue like this when Final Gather was enabled. Does it still happen on RC2?

RC2 is out? where? Also I still get this error without final Gather

RC2 will probably be available mid-next week… Please report this using the bugreporter and post the case number here… Thanks!

Thanks!

There is definitely something going wrong in your scene, likely some cached files getting deleted. We will fix this asap. Thanks for reporting.
Try setting your GI cache size to a high value like 10 Gb, so the files aren’t getting deleted straight away.

It was set to 25Gb at the moment

I didn’t know the existence of this option, but I cleared the cache and it looks to be better now!
