Hey paul, I found a bug when rendering animations. When rendering animations every few frames the render does not complete the complete samples that I set it at. I will try to adjust the sample bit rate multiple times including to a higher level. But I still get the same effect.
See attachments.
I thought I might be just rendering too fast but setting the sample all the way up to 600 I get the same results every few frames. It seems like every few frames it will render one real quickly not to the full sample that was selected.
